* PHPC-2274: Apply libmongocrypt defs to PHP_MONGODB_LIBMONGOCRYPT_CFLAGS
This ensures PHP_MONGODB_LIBMONGOCRYPT_CFLAGS is used instead of PHP_MONGODB_BUNDLED_CFLAGS for libmongocrypt-specific checks.
A libmongoc-specific copy of Endian.m4 has been created to use when building without libmongocrypt, since the endianness check is still required by libmongoc's bundled KMS sources.
* PHPC-2308: Handle unknown and universal cases for AC_C_BIGENDIAN
* PHPC-2049: Bump libmongoc and libmongocrypt submodules
libmongoc master (1.22-dev) now depends on libmongocrypt master (1.5-dev).
libmongoc's bundled zlib library was updated to 1.2.12.
* PHPC-2049: BulkWrite and Query support comment option of any type
MongoDB 4.4+ allows a comment option of any type on most commands. Previously, find required a string type and write commands did not support comment at all. The driver does not validate the option and relies on the server to raise an error.
* Fix title and variable access in BulkWrite and Query let option tests
* Fix grammar in php_phongo_bulkwrite_delete_apply_options comment
* Undefine additional Query option macros
