Added qmake check for presence of RHttpDownloadMgr header
downloadmgrclient.h is not found on S^4 baselines, causing a build failure. This commit is a temporary workaround, which disables progressive download support if the header is not found. The correct solution is to determine whether the RHttpDownloadMgr definition has moved, and if so, to modify the .pro file to include the new path. Task-number: QTBUG-10769 Reviewed-by: TrustMe

<p>Use file access properties to modify the default behavior of the HDF5 library when accessing files. The properties include selecting a virtual file driver (VFD), configuring the metadata cache (MDC), control file locking, etc. These properties are <em>not</em> persisted with files, and can be adjusted at runtime before a file is created or opened. </p><div></div><div>   <a class="anchor" id="table_fapl_id"></a>

<p>The library's metadata cache is fairly conservative about holding on to HDF5 object metadata (object headers, chunk index structures, etc.), which can cause the cache size to grow, resulting in memory pressure on an application or system. When enabled, the "evict on
         close" property will cause all metadata for an object to be immediately evicted from the cache as long as it is not referenced by any other open object.</p>

<p>The metadata cache is a central part of the HDF5 library through which all file metadata reads and writes take place. File metadata is normally invisible to the user and is used by the library for purposes such as locating and indexing data. File metadata should not be confused with user metadata, which consists of attributes created by users and attached to HDF5 objects such as datasets via <a class="el" href="group___h5_a.html">Attributes (H5A)</a> API calls.</p>
<p>Due to the complexity of the cache, a trace/logging feature has been created that can be used by HDF5 developers for debugging and performance analysis. The functions that control this functionality will normally be of use to a very limited number of developers outside of The HDF Group. The functions have been documented to help users create logs that can be sent with bug reports.</p>
<p>Control of the log functionality is straightforward. Logging is enabled via the <a class="el" href="#ga4d7206c5679d7243410058eceae59b2c" title="Sets metadata cache logging options.">H5Pset_mdc_log_options()</a> function, which will modify the file access property list used to open or create a file. This function has a flag that determines whether logging begins at file open or starts in a paused state. Log messages can then be controlled via the <a class="el" href="group___m_d_c.html#ga378fb5863071278b47070cf205f53e67" title="Starts logging metadata cache events if logging was previously enabled.">H5Fstart_mdc_logging()</a> / <a class="el" href="group___m_d_c.html#ga78627b23010f82002b837f4d312bf234" title="Stops logging metadata cache events if logging was previously enabled and is currently ongoing.">H5Fstop_mdc_logging()</a> functions. <a class="el" href="#gaa3a1ca6e294cc5074933239cc3d0e4a3" title="Gets metadata cache logging options.">H5Pget_mdc_log_options()</a> can be used to examine a file access property list, and <a class="el" href="group___m_d_c.html#ga998ebdc7b5190cf3d0fdf2fbe71e9780" title="Gets the current metadata cache logging status.">H5Fget_mdc_logging_status()</a> will return the current state of the logging flags.</p>
<p>The log format is described in the <a href="https://bit.ly/2PG6fNv">Metadata Cache Logging</a> document.</p>

<p>The raw data chunk cache inserts chunks into the cache by first computing a hash value using the address of a chunk and then by using that hash value as the chunk's index into the table of cached chunks. In other words, the size of this hash table and the number of possible hash values are determined by the <code>rdcc_nslots</code> parameter. If a different chunk in the cache has the same hash value, a collision will occur, which will reduce efficiency. If inserting the chunk into the cache would cause the cache to be too big, then the cache will be pruned according to the <code>rdcc_w0</code> parameter.</p>

<p>The default external link open file cache size is 0 (zero), meaning that files accessed via an external link are not held open. Setting the cache size to a positive integer turns on the cache; setting the size back to zero turns it off.</p>
<p>With this property set, files are placed in the external link open file cache cache when they are opened via an external link. Files are then held open until either they are evicted from the cache or the parent file is closed. This property setting can improve performance when external links are repeatedly accessed.</p>
<p>When the cache is full, files will be evicted using a least recently used (LRU) scheme; the file which has gone the longest time without being accessed through the parent file will be evicted and closed if nothing else is holding that file open.</p>
<p>Files opened through external links inherit the parent file's file access property list by default, and therefore inherit the parent file's external link open file cache setting.</p>
<p>When child files contain external links of their own, the caches can form a graph of cached external files. Closing the last external reference to such a graph will recursively close all files in the graph, even if cycles are present. </p><dl class="section user"><dt>Example</dt><dd><p class="startdd">The following code sets up an external link open file cache that will hold open up to 8 files reached through external links:</p>

<p>The library's metadata cache is fairly conservative about holding on to HDF5 object metadata(object headers, chunk index structures, etc.), which can cause the cache size to grow, resulting in memory pressure on an application or system. When enabled, the "evict on
         close" property will cause all metadata for an object to be evicted from the cache as long as metadata is not referenced by any other open object.</p>
<p>This function only applies to file access property lists.</p>
<p>The default library behavior is to not evict on object or file close.</p>
<p>When applied to a file access property list, any subsequently opened object will inherit the "evict on close" property and will have its metadata evicted when the object is closed.</p>

With this driver, data is written to or read from the file synchronously without being cached by the system.</p>
<p>File systems usually require the data address in memory, the file address, and the size of the data to be aligned. The HDF5 library's direct I/O driver is able to handle unaligned data, though that will consume some additional memory resources and may slow performance. To get better performance, use the system function <code>posix_memalign</code> to align the data buffer in memory and the HDF5 function <a class="el" href="#gab99d5af749aeb3896fd9e3ceb273677a" title="Sets alignment properties of a file access property list.">H5Pset_alignment()</a> to align the data in the file. Be aware, however, that aligned data I/O may cause the HDF5 file to be bigger than the actual data size would otherwise require because the alignment may leave some holes in the file.</p>
<p><code>alignment</code> specifies the required alignment boundary in memory.</p>
<p><code>block_size</code> specifies the file system block size. A value of 0 (zero) means to use HDF5 library's default value of 4KB.</p>
<p><code>cbuf_size</code> specifies the copy buffer size.</p>

<p>The multi-file driver enables different types of HDF5 data and metadata to be written to separate files. These files are viewed by the HDF5 library and the application as a single virtual HDF5 file with a single HDF5 file address space. The types of data that can be broken out into separate files include raw data, the superblock, B-tree data, global heap data, local heap data, and object headers. At the programmer's discretion, two or more types of data can be written to the same file while other types of data are written to separate files.</p>
<p>The array <code>memb_map</code> maps memory usage types to other memory usage types and is the mechanism that allows the caller to specify how many files are created. The array contains <a class="el" href="_h5_fpublic_8h.html#a51e588cd954ea2388816bd0818850eb5a3be201777da432df4a8e2c1b618a7566">H5FD_MEM_NTYPES</a> entries, which are either the value <a class="el" href="_h5_fpublic_8h.html#a51e588cd954ea2388816bd0818850eb5a137331d00cf5b0c84ef7dfa725429f90">H5FD_MEM_DEFAULT</a> or a memory usage type. The number of unique values determines the number of files that are opened.</p>
<p>The array <code>memb_fapl</code> contains a property list for each memory usage type that will be associated with a file.</p>
<p>The array <code>memb_name</code> should be a name generator (a <code>printf</code>-style format with a <code>s</code> which will be replaced with the name passed to <a class="el" href="_h5_f_ddevelop_8h.html#a36c22438fe64e0f9e4dc13aec57da21f">H5FDopen()</a>, usually from <a class="el" href="group___h5_f.html#gae64b51ee9ac0781bc4ccc599d98387f4" title="Creates an HDF5 file.">H5Fcreate()</a> or <a class="el" href="group___h5_f.html#gaa3f4f877b9bb591f3880423ed2bf44bc" title="Opens an existing HDF5 file.">H5Fopen()</a>).</p>
<p>The array <code>memb_addr</code> specifies the offsets within the virtual address space, from 0 (zero) to <a class="el" href="_h5public_8h.html#a49742d33813ee38ef58eca9fbeda6b86">HADDR_MAX</a>, at which each type of data storage begins.</p>
<p>If <code>relax</code> is set to 1 (true), then opening an existing file for read-only access will not fail if some file members are missing. This allows a file to be accessed in a limited sense if just the meta data is available.</p>
