This PR aims to add the groundwork to test the precision of libc complex
functions against MPC. I took `cargf` as a test to verify that the infra
works fine.

_I believe, all these macros are necessary and should be documented._
2. **CMake Configuration Update**:
- Updated the `CMakeLists.txt` file to create the necessary directory
for the `netinet` headers.
- Included the `netinet/in` documentation in the Sphinx build
configuration.
3. **Index Update**:
- Updated the `index.rst` file to include a reference to the newly added
`netinet/in` documentation.
**Purpose**:
- This pull request adds documentation for network protocol and address
macros in the `netinet/in` header.
- Updates the CMake configuration to support the new documentation.
**Testing**:

This pull request ensures that the `netinet/in` header macros are
documented and included in the project's documentation, and updates the
CMake configuration to support these changes.
This avoids touching the output file when it hasn't changed. The
cmake build integration now uses this so that touching a .yaml or
.h.def file in ways that don't affect the generated header output
won't cause unnecessary recompilations.
This adds a new main command-line entry point for hdrgen, in the
new main.py. This new interface is used for generating a header.
The old ways of invoking yaml_to_classes.py for other purposes
are left there for now, but `--e` is renamed to `--entry-point`
for consistency with the new CLI.
The YAML schema is expanded with the `header_template` key where
the corresponding `.h.def` file's path is given relative to where
the YAML file is found. The build integration no longer gives
the `.h.def` path on the command line. Instead, the script now
emits a depfile that's used by the cmake rules to track that.
The output file is always explicit in the script command line
rather than sometimes being derived from a directory path.
Now, `ninja docs-libc-html` will re-run docgen.
Previously, we would run docgen offline, and commit the result.
Now we no longer need to do that; docgen is invoked from the
dependencies of the `docs-libc-html` target on demand. This
commit removes the dynamically generated .rst files (keeping
the static ones that haven't been converted to docgen), and
fixes up some mistakes I failed to cleanup recently since I
didn't have such automation in place to catch such bugs.
The .yaml files should live next to the corresponding .h.def
files in libc/include/, rather than next to the implementation of
the tool in libc/utils/hdrgen/. As with the .h.def files, there
is no need for a yaml/ subdirectory under include/. This simpler
layout is more natural for maintenance and also simplifies build
integration outside the LLVM CMake build.
Two extra layers of subdirectory for a handful of single-symbol
Python source files did not improve anything, and it complicated
integration of the hdrgen Python outside the LLVM CMake build.
Summary:
This installs the shared header to the users installation. I couldn't
decide if this should be a standalone thing or use the existing support
in `include/` mostly because this is completely separate from hdrgen
stuff and it's C++.
Usually posix functions have individual doc pages, and each header has its own
list of required macro definitions. Use a simpler key of "in-latest-posix" to
signal that the URL convention can be followed.
Add support for a "removed-in-posix-2008" key which will link to the 2004 docs
for functions like bcmp, bcopy, bzero, index, and rindex from strings.h.
I don't want to add all of these links for pthreads.h, so automating this will
make documenting these go much faster.
bcmp, bcopy, and bzero should be moved from libc/src/string/ to
lib/src/strings/ in order for docgen to use existing conventions to find
whether we implement a function or not.
We should add support to docgen for mentioning glibc extensions (mempcpy) or
extensions from other libcs.
[libc][docs] stub out assert, errno, and locale
These were the remaining c89 library headers (besides string.h and
stdlib.h; I
will split strings.rst in a follow up commit).
The macro support detection in docgen doesn't quite work for some of
these
headers. Add the stubs for these headers for now, and fix up docgen
later.

This commit does a few things:
* creates libc/docs/headers/ and moves all user API related headers under it.
* updates paths and docgen
* updates the top level index to put these headers under a new "Implementation
Status" tab.
* rename some of the files to be foo.rst for foo.h (except strings, which is
currently a mix of string.h and stdlib.h)
* update the heading of some files to be in the form foo.h.
Thanks to the effort of @RoseZhang03 and @aaryanshukla under the
guidance of
@michaelrj-google and @amykhuang, we now have newhdrgen and no longer
have a
dependency on TableGen and thus LLVM in order to start bootstrapping a
full
build.
This PR removes:
- LIBC_HDRGEN_EXE; the in tree newhdrgen is the only hdrgen that can be
used.
- LIBC_USE_NEW_HEADER_GEN; newhdrgen is the default and only option.
- LIBC_HDRGEN_ONLY; there is no need to have a distinct build step for
old
hdrgen.
- libc-api-test and libc-api-test-tidy build targets.
- Deletes all .td files.
It does not rename newhdrgen to just hdrgen. Will follow up with a
distinct PR
for that.

Summary:
We can simply include this header from the shared directory now and do
not need to have this level of indirection. Simply stash it with the
other libc opcode handlers.
If we were able to move the printf handlers to the shared directory then
this could just be a header as well, which would HEAVILY simplify the
mess associated with building the RPC server first in the projects
build, then copying it to the runtimes build.
Summary:
We currently have an unnecessary level of indirection when initializing
the RPC client. This is a holdover from when the RPC client was not
trivially copyable and simply makes it more complicated. Here we use the
`asm` syntax to give the C++ variable a valid name so that we can just
copy to it directly.
Another advantage to this, is that if users want to piggy-back on the
same RPC interface they need only declare theirs as extern with the same
symbol name, or make it weak to optionally use it if LIBC isn't
avaialb.e
Summary:
The AMDGPU backend can handle wavefront sizes of 32 and 64, with the
native hardware preferring one or the other. The user can override the
hardware with `-mwavefrontsize64` or `-mwavefrontsize32` which
previously wasn't handled. We need to know the wavefront size to know
how much memory to allocate and how to index the RPC buffer. There isn't
a good way to do this with ROCm so we just use the LLVM support for
offloading to check this from the image.
Summary:
This patch removes much of the `llvmlibc_rpc_server` interface. This
pretty much deletes all of this code and just replaces it with including
`rpc.h` directly. We still maintain the file to let `libc` handle the
opcodes, since those depend on the `printf` impelmentation.
This will need to be cleaned up more, but I don't want to put too much
into a single patch.
Summary:
Previous patches have made the `rpc.h` header independent of the `libc`
internals. This allows us to include it directly rather than providing
an indirect C API. This patch only does the work to move the header. A
future patch will pull out the `rpc_server` interface and simply replace
it with a single function that handles the opcodes.
