This API converts a config.h.in file into config.h. This is useful when
introducing a build.zig file to an existing C/C++ project that is
configured with autotools or cmake.
The cmake syntax is not implemented yet.

In order to add tests for this I need to implement an HTTP server in the
standard library (#910) so that's probably the next thing I'll do.
RFC 9110 section 15:
Values outside the range 100..599 are invalid. Implementations often use
three-digit integer values outside of that range (i.e., 600..999) for
internal communication of non-HTTP status (e.g., library errors). A
client that receives a response with an invalid status code SHOULD
process the response as if it had a 5xx (Server Error) status code.
The resolvePosix and resolveWindows routines changed behaviour in an
earlier commit so that the return value is not always an absolute path.
That caused the relativePosix and relativeWindows to return a relative
path that is not correct.
The change in behaviour mentioned above would cause a local cache-dir to
be created in the wrong directory when --cache-dir was specified for a
build.
* std.http.Status.Class: add a "nonstandard" enum tag. Instead of
having `class` return an optional value, it can potentially return
nonstandard.
* extract out std.http.Client.Connection from std.http.Client.Request
- this code abstracts over plain/TLS only
- this is the type that will potentially be stored in a client's LRU
connection map
* introduce two-staged HTTP header parsing
- API users can rely on a heap-allocated buffer with a maximum limit,
which defaults to 16 KB, or they can provide a static buffer that
is borrowed by the Request instance.
- The entire HTTP header is buffered because there are strings in
there and they must be accessed later, such as with the case of
HTTP redirects.
- When buffering the HTTP header, the parser only looks for the
\r\n\r\n pattern. Further validation is done later.
- After the full HTTP header is buffered, it is parsed into
components such as Content-Length and Location.
* HTTP redirects are handled, with a maximum redirect count option that
defaults to 3.
- Connection: close is always used for now; implementing keep-alive
connections and an LRU connection pool in std.http.Client is a task
for another day.

This is simply a small convenience wrapper around
'meta.fieldInfo(T, .field).type'. However, this operation is common
enough that it makes sense to have its own function for.
Although RFC 8446 states:
> Each party MUST send a "close_notify" alert before closing its write
> side of the connection
In practice many servers do not do this. Also in practice, truncation
attacks are thwarted at the application layer by comparing the amount of
bytes received with the amount expected via the HTTP headers.
This allows for a more optimal std.crypto.tlcsprng codepath.
Without it a an "incorrect alignment" panic is triggered from
crypto.tlcsprng which aligns a threadlocal but it's actually
not aligned, thus detected by the safety check.
It appears that LLVM-IR does attribute the storage with alignment
but it is ultimately not respected in the final binary for netbsd
and dragonfly.
- per darwin-xnu source, fcntl F_GETPATH will return ENOSPC when path
exceeds either user-supplied buffer or system MAXPATHLEN
- macOS does not document this (and other) possible errno values
