Summary:
Use inline variables to avoid the function-pointer trick.

Use explicit default constructors per the types in the standard.

Import the names from the standard in C++17.

This allows declaring a function with tags from one namespace and calling the function with tags from the other namespace in C++17.

Summary:
`__folly_memcpy` already behaved as `memmove` for n <= 256B.

For n > 256B and overlapping buffers `__folly_memcpy` did some work
- it determined the size is large enough for 128B AVX loads/stores
- it has already copied the first 128B and the last 128B in YMM registers

but then discarded it and fell back on `memmove`.

Instead of wasting this work, forward copy (dst < src) or backward copy (dst > src).
- use unaligned loads + aligned stores, but not non-temporal stores
- for dst < src forward copy in 128 byte batches:
-- unaligned load the first 32 bytes & last 4 x 32 bytes
-- forward copy (unaligned load + aligned stores) 4 x 32 bytes at a time
-- unaligned store the first 32 bytes & last 4 x 32 bytes
- for dst > src backward copy in 128 byte batches:
-- unaligned load the first 4 x 32 bytes & last 32 bytes
-- backward copy (unaligned load + aligned stores) 4 x 32 bytes at a time
-- unaligned store the first 4 x 32 bytes & last 32 bytes

Summary:
Update to a newer python that builds on macOS Big Sur, make eden_scm depend on it and use it from PATH

python 3.8 requires libffi which is reference via its pkg-config setup,  however python's pkg-config libffi detection is broken (https://bugs.python.org/issue34823) with the documented workaround requiring an environment variable to be passed into its ./configure step, which is why this change also adds a feature to AutoconfBuilder

With the updated python in place I was able to remove disable_env_override_pkgconfig = 1
disable_env_override_path = 1 from the eden_scm config so that it actually uses the pkg-configs, PATHs and other settings from its dependencies. This should make future python and other dependency upgrades much simpler.

Summary: In generic algorithms parameterized by a mutex type, it may be the case that a shared lock is desired if the mutex is a shared mutex and a unique lock is desired otherwise. This allows a wider range of mutex type arguments rather than just permitting shared mutex types. A hybrid lock may be used with read-only access to data; when the mutex type is shared, the lock would be optimized to a shared lock, but when the mutex type is non-shared, the lock would fall back to a unique lock. This may be helpful since writes may dominate reads in some cases and unique locks on non-shared mutex types may be faster than unique locks on shared mutex types.

Summary:
Most referenced repos have moved from master to main as default branch, so flip the default in getdeps.

As well as tidying things up, this means more manifests will be able to use the pinned git commit hash for a dependency that shipit generates (e.g. build/deps/github_hashes/facebook/folly-rev.txt). This is because a "rev = " setting in the manifest is treated as a dynamic override in GitFetcher.__init__ and this diff reduces the number of such overrides.
