[svn-r20065] Description:

    Bring changes from Coverity branch to trunk:

r19975:
Fixed potential mem leak at H5O_attr_open_by_name

r19980:
Fix coverity issue 792.
Free tmp_env_prefix in H5Lexternal.c line 365 if it is not NULL but its contents are 0 when it goes out of scope.

r20039:
Eliminate warnings about nested extern and implicit declarations of parallel_print and address Coverity defects 712-781 by #including h5tools_utils.h in h5diff_array.c, h5diff_attr.c, h5diff_dset.c and h5diff_util.c.

r20046:
Purpose: Address TOCTOU warnings in h5jam and h5unjam

Description: Coverity is afraid that the state of the input file could change
between the call to stat() and the call to open().  This is called a time-of-
check time-of-use (TOCTOU) vulnerability.  Modified stat calls to fstat which
uses an open file pointer so it (hopefully) won't complain any more.

r20047:
Addressed coverity issues 135-137, 462-464.  Local pointers that needed to be freed in case of error were moved out of a switch statement in src/H5Tnative.c, set to NULL, and checked before freeing.

Tested on:
    Mac OS X/32 10.6.6 (amazon) w/debug & production
    (h5committested on Coverity branch)
