Fix for split VFD and file cleanup when testing H5Fis_hdf5 and H5Fis_accessible in tfile.c.
Improvements to the H5Fis_accessible() and H5Fis_hdf5() tests in tfile.c. * General code tidying. * Expanded tests to work with multi-file VFDs.
* commit '62198c2436ac3787afb49fa990d1ba8204264dba':

* commit '53a5c3be903ce7c24d02a6bd3a8d9b07a3f82404':
Change the checking to H5I_INVALID_HID in test_attr_dense_rename().
Fix for HDFFV-10579 H5Arename fails when creation order of attributes is tracked. The attribute needs to be removed from the creation order index v2 B-tree before re-inserting the renamed attribute via H5A__dense_insert().

Minor fix: removal of unnecessary enum values.
Minor fixes: updating the test vds_env.c according to the set up of vds.c.
Left out this file in previous commit.
HDFFV-10658 - setting and getting properties in API context: 1. switched to use the existing H5F_prefix_open_t for enum type; 2. put the common private function used by external.c and external_env.c into external_common.c
This commit basically has the following changes: 1. restored the datatype, dataspace, and LCPL of the dataset for VOL connector back to the properties. 2. splitted external.c and vds.c because they called HDsetenv in the program, instead using shell scripts to set the environment variables. 3. changed H5CX_get_vds_prefix and H5CX_get_ext_file_prefix to use H5P_peek instead of H5P_get.
HDFFV-10658: I left out this file in my previous commit.
HDFFV-10658: 1. moving HDgetenv to dataset initialization stage to reduce the overhead; 2. restoring the retrieval of three vol properties to H5P_get instead of using API context to prepare for Quincey's upcoming refactoring work.
