[libc][docs] Add net/if.h documentation by referring to POSIX standards (#122406)
This pull request introduces the following changes to the project with
reference to issue ( #122006 ):

1. **Documentation Update**:
- Added a new YAML file `if.yaml` under `net` to document network
interface functions and macros.
   - The `if.yaml` file includes the following functions and macros:
     - Functions:
       - `if_freenameindex`
       - `if_indextoname`
       - `if_nameindex`
       - `if_nametoindex`
     - Macros:
       - `IF_NAMESIZE`

2. **CMake Configuration Update**:
- Updated the `CMakeLists.txt` file to create the necessary directory
for the `net` headers.
- Included the `net/if` documentation in the Sphinx build configuration.

3. **Index Update**:
- Updated the `index.rst` file to include a reference to the newly added
`net/if` documentation.

**Purpose**:
- This pull request adds documentation for network interface functions
and macros, ensuring they are included in the project's documentation.
- Updates the CMake configuration to support the new documentation.

**Testing**:
- Verified that the new YAML file is correctly referenced in the
`index.rst`.
- Ensured that the documentation builds without errors and includes the
new network interface documentation.

[libc][docs] Add netinet/in header documentation by referring to POSIX standards (#122411)
This pull request introduces the following changes to the project with
reference to ( #122006 ):

1. **Documentation Update**:
- Added a new YAML file `in.yaml` to document network protocol and
address macros.
   - The `in.yaml` file includes the following macros:
     - `IPPROTO_IP`
     - `IPPROTO_IPV6`
     - `IPPROTO_ICMP`
     - `IPPROTO_RAW`
     - `IPPROTO_TCP`
     - `IPPROTO_UDP`
     - `INADDR_ANY`
     - `INADDR_BROADCAST`
     - `INET_ADDRSTRLEN`
     - `IPV6_JOIN_GROUP`
     - `IPV6_LEAVE_GROUP`
     - `IPV6_MULTICAST_HOPS`
     - `IPV6_MULTICAST_IF`
     - `IPV6_MULTICAST_LOOP`
     - `IPV6_UNICAST_HOPS`
     - `IPV6_V6ONLY`
     - `IN6_IS_ADDR_UNSPECIFIED`
     - `IN6_IS_ADDR_LOOPBACK`
     - `IN6_IS_ADDR_MULTICAST`
     - `IN6_IS_ADDR_LINKLOCAL`
     - `IN6_IS_ADDR_SITELOCAL`
     - `IN6_IS_ADDR_V4MAPPED`
     - `IN6_IS_ADDR_V4COMPAT`
     - `IN6_IS_ADDR_MC_NODELOCAL`
     - `IN6_IS_ADDR_MC_LINKLOCAL`
     - `IN6_IS_ADDR_MC_SITELOCAL`
     - `IN6_IS_ADDR_MC_ORGLOCAL`
     - `IN6_IS_ADDR_MC_GLOBAL`

_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**:
- Verified that the new YAML file is correctly referenced in the
`index.rst`.
- Ensured that the documentation builds without errors and includes the
new network interface documentation.

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.

[docs][libc] Add AIO documentation refering POSIX and include in build (#122219)

[libc][docgen] regen docgen via cmake (#119628)
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.

[libc][docgen] simplify posix links (#119595)
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.

[libc][docs] split "String Functions" into string.h, strings.h, stdlib.h, and inttypes.h (#118860)
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] add missing c99 docs (#119239)
Looks like we were missing docs for:
- float.h
- wchar.h
- wctype.h

Which AFAICT were added in ISO C99.

[libc][docs] stub out assert, errno, and locale (#118852)
[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.

[libc][docs] reorganize documentation (#118836)
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.
