This is a non functional change, it allows:
- Getting rid of `unix_features_aggregator`
- Have a single blob describing the features
- Fix wrong mocking of `hwcaps`
Downside: abuse of macros makes the code slightly magical and harder to understand.
It think it's still an improvement over the current situation as there's less repetition and less chances to get something wrong.
Fixes#4. This is based on #115 with a few modifications:
- Removed use of __builtin_cpu_supports since it relies on cpuid and doesn't improve on the current situation,
- Added detection for all of sse, sse2, sse3, ssse3, sse4_1 and sse4_2,
- Added tests for Atom, Nehalem, and P3 processors,
Thx to @gadoofou87 for providing the original PR.
It also removes the need for #92

Most of them, with the exception of _open() -> _sopen_s() are about
questionable implicit casts. Fixing the types and adding explicit casts
to explicitly mark the intention (and silence the warnings in the process)
* Add support for leaf4 on Intel's x86 arch
* Update cpuinfo_x86.h
* Fix typo
* Force compiler to use C99
* Add Intel x86 leaf2 support
* Fixes after review
* Fix review comments
* First implementation of ndk_compat
* Restrict building of linux_based_hardware_detection to UNIX
* Fix variable declaration and printf formatting
* Restrict ndk compat to UNIX style systems
* Restrict cpu_mask index to 32
* Fix values display in ndk-compat-test
* Addressing comments
