* Function: h5tools_fopen
*
* Purpose: Opens file FNAME using the specified flags and FAPL.
*
* The 'use_specific_driver' parameter is used to control the
* VFD/VOL connector that this routine uses to open the file
* with. If 'use_specific_driver' is set to TRUE, this routine
* assumes that the caller has already set a specific VFD or VOL
* connector on the given FAPL and will attempt to directly use
* the FAPL for opening the file. We assume that the caller knows
* what they are doing; if the file is unable to be opened using
* that FAPL, this routine will return H5I_INVALID_HID.
*
* However, if 'use_specific_driver' is set to FALSE, this
* routine assumes that the caller HAS NOT set a specific VFD or
* VOL connector on the given FAPL and will instead loop through
* the various available VFL drivers and VOL connectors trying to
* open FNAME.
*
* The list of available VFL drivers is as follows:
* - If the HDF5 library is version 1.2 or less, then we have
* only the SEC2 driver to try out.
* - If the HDF5 library is greater than version 1.2, then we
* have the FAMILY, SPLIT, and MULTI drivers to play with.
*
* The list of available VOL connectors is as follows:
* - "Native" VOL connector
* - Pass-through VOL connector
*
* Return:
* On success, returns a file ID for the opened file. If DRIVERNAME is
* non-null and the native VOL connector is the terminal connector,
* then the first DRIVERNAME_SIZE-1 characters of the driver name are
* copied into the DRIVERNAME array and null terminated. If the
* native VOL connector is NOT the terminal connector, then the first
* byte of DRIVERNAME will be set to the null terminator.
*
* On failure, the function returns H5I_INVALID_HID and DRIVERNAME
* will not be set.
