Replace global storage TLS with new interface

2020-12-08T14:53:13+00:00

threads: git_tls_data to git_tlsdata

2020-12-08T14:53:13+00:00

Use a no-allocation approach to the TLS data abstraction.

win32: provide macros for calling conventions

2020-12-08T14:50:06+00:00

Provide more clarity for Win32 calling conventions - now that we always
compile to __cdecl on Win32, we'll define that as the the libgit2
calling convention.  Also offer NTAPI (__stdcall) calling conventions
for things that need callbacks from NTAPI code (eg fiber-local storage).

Implement generic TLS interface

2020-12-06T01:08:22+00:00

This adds a generic TLS interface for anyone to store TLS data. It is designed to work regardless of whether threading support is built into the library or not.

Nobody in the library should directly interface with the data on the TLS struct, so it's been built to be opaque even in the library.

Requires the allocator to be initialized before use.

threads: rename thread files to thread.[ch]

2020-12-06T01:08:22+00:00

threads: give atomic functions the git_atomic prefix

2020-12-06T01:08:22+00:00

threads: rename git_atomic to git_atomic32

2020-12-06T01:08:22+00:00

Clarify the `git_atomic` type and functions now that we have a 64 bit
version as well (`git_atomic64`).

util: move git_online_cpus into util

2020-12-06T00:55:35+00:00

The number of CPUs is useful information for creating a thread pool or a
number of workers, but it's not really about threading directly.  Evict
it from the thread file
