[PATCH v4 0/7] MR4377: Reimplement msvcrt env functions to match native.
This serie: - adds a couple of msvcrt env tests (mainly env block inheritance) - introduces env tests for ucrtbase - reimplement most of the env related functions to mimic native behavior (basically when env is modified, native crt uses a per-variable entry allocation block (instead of having pointers inside a single chunk of memory). This fixes programs which keep a pointer on returned getenv() string and expect that pointer content is not modified when other variables in env are modified. @piotr: from previous version - I dropped the synchronization of \_environ and \_wenviron hence requiring the duplication of most of the code in ansi/unicode versions - I also tested the changes with unicode crt startup code (you can find in [1] this MR extended with this test code but I don't think we want to push it upstream) - there are some init code changes because of ucrtbase tests and unicode crt startup tests [1] https://gitlab.winehq.org/epo/wine/-/tree/mr-crt-env-full?ref_type=heads -- v4: msvcrt: Fix ucrtbase environment initialization. msvcrt: Allocate environment variables in separate allocation chunks. msvcrt: Lazily initialize ___winitenv. msvcrt: Factor out env_get_index helper. msvcrt: Factor out env_get_index helper. ucrtbase/tests: Introduce environment tests. msvcrt/tests: Test passing environment in child process. https://gitlab.winehq.org/wine/wine/-/merge_requests/4377
