* 1. HDFFV-10830 part 2, move AC_CHECK_HEADERS([szlib.h] after
            AC_CHECK_LIB([sz], [SZ_BufftoBuffCompress] to avoid compiling
                H5Z.c with szlib.h after its path is removed from AM_CPPFLAGS.
    2. Remove unnecessary links to ${HDF5_TOOLS_LIB_TARGET} in
    utils/mirror_vfd/CMakeLists.txt that prevent building HDF5 with tools
    disabled.
* Trivialities noticed while normalizing 1.10
* Minor copy edits to comments -- no code changes.
* Minor refactoring based on 1.10 normalization work
* Adds fix for H5Fstart_swmr_write lock issue
* Moves lock flag to H5F_shared_t and adds test.
* Fix HDFFV-11101

    Description
        Added initialization to local structs in the src function
        H5MF_settle_raw_data_fsm() and the test function test_bt2_hdr_fd()
        to prevent the following error in two different occurrences:
            MemorySanitizer: use-of-uninitialized-value
    Platforms tested:
        Linux/64 (jelly)
        Linux/64 (platypus)

* Only initialize the contiguous or compact I/O info struct when needed.
* Trivial whitespace change to H5Pencdec.c
* Fixed typo
* Removes inappropriate file locking call
* Fixes CMake issue with file locking variable
