mbedtls: fix building with v3 in CMake Unity mode

Before this patch the internal feature detection macro
`HAS_MBEDTLS_RESULT_CODE_BASED_FUNCTIONS` was defined in three files,
with an incomplete logic in one of them. In Unity mode that spilled
into another source file and broke the build.

multi: introduce SETUP state for better timeouts

Since we can go to the CONNECT state from PENDING, potentially multiple
times for a single transfer, this change introdues a SETUP state that
happens before CONNECT when doing a new transfer.

Now, doing a redirect on a handle goes back to SETUP (not CONNECT like
before) and we initilize the connect timeout etc in SETUP. Previously,
we would do it in CONNECT but that would make it unreliable in cases
where a transfer goes in and out between CONNECT and PENDING multiple
times.

SETUP is transient, so the handle never actually stays in that state.

Additionally: take care of timeouts of PENDING transfers in
curl_multi_perform()

docs: clarify CURLOPT_MAXFILESIZE and CURLOPT_MAXFILESIZE_LARGE

The bounds of the size parameter were not specified, and nor was it
specified how to disable the maximum file size check.

The documentation also incorrectly stated that CURLOPT_MAXFILESIZE
always returns CURLE_OK and that CURLOPT_MAXFILESIZE_LARGE only returns
CURLE_OK or CURLE_UNKNOWN_OPTION.

It also did not mention what the default value is, which is zero. This
commit updates the documentation to make note of all these things.

multi: timeout handles even without connection

When there is a "change" in a multi handle and pending handles are moved
back to the main list to be retested if they can proceed further (for
example a previous transfer completed or a connection has a confirmed
multiplexed state), the timeout check in multi_runsingle() would not
trigger because it required an established connection.

This could make a pending tranfer go back to pending state even though
it had been "in progress" for a longer time than permitted. By removing
the requirement for an associated connection, the timeout check will be
done proper even for transfers that has not yet been assigned one.

mprintf: check fputc error rather than matching returned character

OS/400 ascii fputc wrapper deviates from the posix standard by the
fact that it returns the ebcdic encoding of the original ascii
character. Testing for a matching value for success will then always
fail.

This commit replaces the chariacter comparison by an explicit error
return check.

lib: merge `ENABLE_QUIC` C macro into `USE_HTTP3`

Before this patch `lib/curl_setup.h` defined these two macros right
next to each other, then the source code used them interchangeably.

After this patch, `USE_HTTP3` guards all HTTP/3 / QUIC features.
(Like `USE_HTTP2` does for HTTP/2.) `ENABLE_QUIC` is no longer used.

This patch doesn't change the way HTTP/3 is enabled via autotools
or CMake. Builders who enabled HTTP/3 manually by defining both of
these macros via `CPPFLAGS` can now delete `-DENABLE_QUIC`.

build: prefer `USE_IPV6` macro internally (was: `ENABLE_IPV6`)

Before this patch, two macros were used to guard IPv6 features in curl
sources: `ENABLE_IPV6` and `USE_IPV6`. This patch makes the source use
the latter for consistency with other similar switches.

`-DENABLE_IPV6` remains accepted for compatibility as a synonym for
`-DUSE_IPV6`, when passed to the compiler.

`ENABLE_IPV6` also remains the name of the CMake and `Makefile.vc`
options to control this feature.

Limited to x64, because for build testing the additional CPUs don't add
much value compared to the extra build time. They can be enabled easily
if deemed useful.

To the extent of curl-for-win configuration options, it's trivial to add
further build combinations.
