Closes#18964
During the SOCKS connect phase, the `iobuf` is used to receive repsonses
from the server. If the server sends more bytes than expected, the code
discarded them silently.
Fix this by advancing the iobuf only with the length consumed.

Closes#18938
GNU GSS offers `gss.h`; do not check for `gssapi.h`. `gssapi.h`
was originally published by Heimdal, and later MIT Kerberos also added it
for Heimdal compatibility.
Closes#18993
Previous minimum was: 1.2.4 (2002-02-28)
- assume `gssapi/gssapi.h` header for MIT Kerberos.
Drop logic detecting this header, and drop alternate logic including
a bare "gssapi.h". Bare `gssapi.h` is Heimdal-specific. MIT Kerberos
added support for it for Heimdal compatibility on 2006-11-09,
redirecting to `gssapi/gssapi.h`. MIT Kerberos supported the latter
header in the 1990s already.

Ref: d119352001 (2006-11-09)
- configure.ac: stop using `HAVE_GSSAPI_GSSAPI_H`.
Added in 2010 to support "ancient distros such as RHEL-3" where
`gssapi/gssapi_krb5.h` did not include `gssapi/gssapi.h`.
MIT Kerberos includes it since commit:
d9e959edfa (2003-03-06)
Released in 1.3 (2003-07-08).
Bump minimum required version to avoid this issue.

The cmake build is running runtests with valgrind. The autotools one is
running scan-build.
Also:
- ignore two memleaks with GNU GSS detected by valgrind.
- add comment on support status of `GSS_C_DELEG_POLICY_FLAG`.
Closes#19008
It's a legacy MIT Kerberos header that's no longer used by curl since:
355bf01c82 (2015-01-09)
There were still mentions of it after this patch, when using versions
<1.2.3, but those versions aren't supported since:
9918541795 (2008-06-12)
This header remains in use by autotools and cmake to detect MIT Kerberos
(vs. Heimdal, which doesn't have it.)

The libssh API uses a 32 bit type for datestamp, so instead of just
force-typecast it, make sure it gets capped at UINT_MAX if the value is
larger.

Closes#18989
curl requires 1.2.4 or newer.
Also:
- vms: stop defining `gss_nt_service_name`. Added in
f9cf3de70b, symbol not used in curl code
since 355bf01c82.
Closes#18978
The file size is weirdly returned in a 150 or 126 response as "XXX
bytes" mentioned somewhere in the response string. This is a rewrite of
the size scanner to replace the strange strstr() + backwards search from
before with a plain forward search until '[number] + " bytes"' is a
match.
Triggered by a report by Joshua Rogers about the previous parser.
Closes#18984
In one c-ares call the passed in pointer was used and not the new
duplicated one. This is probably fine but might as well use the new
pointer as all the other calls do, which will survive longer.

Previously, if for example the nonce would end with "realm=" etc it
would get the wrong piece, due to the naive parser.

- Add an example that demonstrates per-transfer verbose logging to
memory.
The transfer's log is written to disk only if the transfer fails.
Closes https://github.com/curl/curl/pull/18668
- Keep data from a failed download instead of discarding it on retry in
some limited cases when we know it's ok (currently only HTTP 200/206).
Prior to this change on failed transfer the tool truncated any outfile
data written before retrying the transfer. This change adds an exception
for HTTP downloads when the user requested auto-resume, because in that
case we can keep the outfile data and resume from the new position.

Fixes https://github.com/curl/curl/issues/18035
Closes https://github.com/curl/curl/pull/18665
Opening the remote file with O_APPEND while attempting to resume causes
all writes to be forced to EOF on servers/implementations where O_APPEND
semantics override a prior seek(). As a result, sftp_seek64() is ignored
and the resumed data is appended, duplicating/corrupting the file.
Fix by:
- Using O_WRONLY (without O_APPEND) when resume_from > 0.
- Skipping the seek entirely if remote_append mode is requested.

Closes#18934
The kerberos5 library Heimdal is one of three GSS libraries curl support.
It has a memory leak triggered by the new test in #18917 and the project
seems mostly abandoned.
Drop support and steer users to the MIT krb5 or GNU GSS libraries.
