Fuchsia is a microkernel-like OS. It strategically implements
some POSIX and Unix APIs to promote software re-use.
It considers itself POSIX lite.
"In order to reduce the amount of source modification needed to
run on Fuchsia, Fuchsia offers a POSIX compatibility layer, POSIX
Lite, that this software can target. POSIX Lite is layered on
top of the underlying Fuchsia System ABI as a client library.
However, POSIX Lite is not a complete implementation of POSIX."
In the case of Fuchsia + src/util, these heavy-weight POSIX
functions shouldn't be used:
- file descriptors
- syslog.h
- signals
- process creation
To differentiate POSIX Lite, which Fuchsia and all heavy-weight
POSIX implementations support, add DETECT_OS_POSIX_LITE.
The use case is incrementally upstreaming functionality used in
downstream drivers (lavapipe, ..). Being in-tree for obvious
patches helps until the full driver can be merged.

Looking at each usage of DETECT_OS_UNIX, it's more about the POSIX API usage, not the
Unix-like OS, so let's rename it
And for POSIX it's a standard to claim which API present, but for UNIX there is no such thing

"__ANDROID__ is defined by the compiler. It is defined for
all Android targets."
"ANDROID is set by some build systems, and not in any reliable
manner (in AOSP it actually just means that you're in AOSP; it's
set even when you're building host code for Windows, so it
doesn't mean much of anything)."
https://github.com/android/ndk/issues/407https://github.com/android/ndk/issues/807
Since the toolchain provides __ANDROID__ for actual Android
targets, standalone NDK and Soong builds should work.
The Mesa CI uses a combination of the NDK toolchain, internal
Android stubs and a Debian sysroot when compile testing Android.
Long-term, it should be possible to remove ANDROID and use
DETECT_OS_ANDROID everywhere.

Mostly copied from src/gallium/include/pipe/p_config.h, so I kept its
copyright and authorship.
Other than the obvious rename, the big difference is that these are
always defined, to be used as `#if DETECT_OS_LINUX`.
