curl.1: mention "global" flags
Mention options that are "global". A global command line option is one
that doesn't get reset at --next uses and therefore don't need to be
used again.
time_t representation is undefined and varies on bitsize and signedness,
and as of C11 could be even non integer.
instead of casting to unsigned long (which would truncate in systems
with a 32bit long after 2106) use difftime to get the elapsed time as a
double and print that (without decimals) instead.
alternatively a cast to curl_off_t and its corresponding print
formatting could have been used (at least in POSIX) but portability and
curl agnostic code was prioritized.

docs: change max-filesize caveat again
- Add protocols field to max-filesize.d.
- Revert wording on unknown file size caveat and do not discuss specific
protocols in that section.
Partial revert of ecf0225. All max-filesize options now have the list of
protocols and it's clearer just to have that list without discussing
specific protocols in the caveat.
commit 29c7cf79e8b44cf (shipped in 7.78.0) introduced a problem by
assuming that LIB_H2 does not have any leading whitespace. At least
OpenBSD's native pkg-config can produce such whitespace, though:
$ pkg-config --libs-only-l libnghttp2
-lnghttp2
As a result, the configure check for libnghttp2 will erroneously fail.

connect: fix wrong format specifier in connect error string
0842175 (not in any release) used the wrong format specifier (long int)
for timediff_t. On an OS such as Windows libcurl's timediff_t (usually
64-bit) is bigger than long int (32-bit). In 32-bit Windows builds the
upper 32-bits of the timediff_t were erroneously then used by the next
format specifier. Usually since the timeout isn't larger than 32-bits
this would result in null as a pointer to the string with the reason for
the connection failing. On other OSes or maybe other compilers it could
probably result in garbage values (ie crash on deref).

Write out directories rather than using the dirs abbrevation. Also
use plural form consistently, even if the code in the end might just

docs: make the documentation for --etag-save match the program behaviour
When using curl with the option `--etag-save` I expected it to save the
ETag without its surrounding quotes, as stated by the documentation in
the repository and by the generated man pages.
My first endeavour was to fix the program, but while investigating the
history of the relevant parts, I discovered that curl once saved the
ETag without the quotes. This was undone by Daniel Stenberg in commit
`98c94596f5928840177b6bd3c7b0f0dd03a431af`, therefore I decided that in
this case the documentation should be adjusted to match the behaviour of
curl.
The changed save behaviour also made parts of the `--etag-compare`
documentation wrong or superfluous, so I adjusted those accordingly.
easy: during upkeep, attach Curl_easy to connections in the cache
During the protocol-specific parts of connection upkeep, some code
assumes that the data->conn pointer already is set correctly. However,
there's currently no guarantee of that in the code.
This fix temporarily attaches each connection to the Curl_easy object
before performing the protocol-specific connection check on it, in a
similar manner to the connection checking in extract_if_dead().
- curl_setup.h: all references to mbedtls_md4* functions and structures
are in the md4.c. This file already includes the <mbedtls/md4.h> file
along with the file existence control (defined (MBEDTLS_MD4_C))
- curl_ntlm_core.c: unnecessary include - repeated below
Wyatt OʼDay reported in #7385 that mbedTLS isn't backwards compatible
and curl no longer builds with it. Document the need to fix our support
until so has been done.
docs: fix inconsistencies in EGDSOCKET documentation
Only the OpenSSL backend actually use the EGDSOCKET, and also use
TLS consistently rather than mixing SSL and TLS. While there, also
fix a minor spelling nit.

Revert "ftp: Expression 'ftpc->wait_data_conn' is always false"
The reverted commit introduced a logic error in code that was
correct.
The client using libcurl would notice the error since FTP file
uploads in active transfer mode would somtimes complete with
success despite no transfer having been performed and the
"uploaded" file thus not being on the remote server afterwards.
The FTP server would notice the error because it receives a
RST on the data connection it has established with the client
before any data was transferred at all.
The logic error happens if the STOR response from the server have
arrived by the time ftp_multi_statemach() in the affected code path
is called, but the incoming data connection have not arrived yet.
In that case, the processing of the STOR response will cause
'ftpc->wait_data_conn' to be set to TRUE, contradicting the comment
in the code. Since 'complete' will also be set, later logic would
believe the transfer was done.
In most cases, the STOR response will not have arrived yet when
the affected code path is executed, or the incoming connection will
also have arrived, and thus the error would not express itself.
But if the speed difference of the device using libcurl and the
FTP server is exactly right, the error may happen as often as in
one out of hundred file transfers.
