* feat: add linux distributions to os context

* Clean up test-allocations like a good boy

* separate os-dependent unit-test sources

* platform-specfic testing is decided in the translation-units

* Exclude Android too

* Add documented fallback

* Ensure we exhausted the snapshot

* DeMorgan

* format

* add valgrind exception for false positive when memmove is an ifunc resolving to memcpy

* Make sure that distributions are only added in Linux not any Unix

* Make sure we don't leak in the error paths

* Clean up the fall-back from /etc/os-release to /usr/lib/os-release

* attribute derivative work

* apply PR feedback

* Extract slice to buffer handling in a new sentry_slice_t function.

* Make sure we can read a full line of max value and max key.

This is a hugely hypothetical target, since the max values are far
beyond all the test data we currently observed, but still.

* fix classic buffer continuity bug.

* extract parse_line_into_object...

...to separate parsing/output from buffer management.

* ensure line update if we hit the buffer-end correctly.

* add support for os-release files that don't end with a newline.

* Add comments to the subtler buffer management aspects.

* Add a list of tested distribution names for documentation

* Add back eof-newline to valgrind exceptions.

* Adapt test to new entry in fixture.

* include sentry_utils in sentry_os only on Linux

* Ensure we find close() in unistd.h by including it explicitly.

* include sentry_utils in sentry_os on Windows too

* use unistd.h in sentry_os only for Linux

* flattened distribution payload fields

* format

* incref for get_by_key calls

* decref no longer copied os_dist
