The code obtained a pointer resp via Curl_bufq_peek(), but called
Curl_bufq_skip() before it would access them in the failf() call.
The Curl_bufq_skip() call can trigger prune_head which may free or
recycle the chunk that resp points into.

Use LDAP_OPT_SUCCESS for ldap_get_option, as done in the other calls.
ber_sockbuf_ctrl returns 1 on success so reverse the logic.

Adopt ngtcp2_conn_get_stream_user_data which has been available since
ngtcp2 v1.17.0. This improves the time complexity of searching
h3_stream_ctx from O(n) to O(1) where n is the number of stream.

- Do not leak memory on failed setting algorithm cipher list.
Discovered by ZeroPath.
- Do not free backend->cred after failed AcquireCredentialsHandle.
backend->cred is always freed later, during cleanup.

- do not pre-fill `HAVE_LINUX_TCP_H` on Linux.
`linux/tcp.h` is a Linux kernel userspace header. It's likely
installed when using glibc and likely missing by default when using
something else, e.g. MUSL (e.g. on Alpine).
Therefore always detect it for Linux targets, and only pre-fill it for
non-Linux ones.
- do not pre-fill `HAVE_GLIBC_STRERROR_R` on Linux.
To fix it for non-glibc envs, e.g. MUSL (e.g. on Alpine).
Note, the pre-fill option is a disabled by default, internal option and
strongly not recommended outside of curl development.
Closes#19116
In providercheck(), when failing to open the "store", the exit path
would not previously free the created UI_METHOD and instead leak this
resource.

Closes#19114
The -F option allows users to provide a file with a set of headers for a
specific formpost section. This code used old handcrafted parsing logic
that potentially could do wrong.
Rewrite to use my_get_line() and dynbuf. Supports longer lines and
should be more solid parsing code.
Gets somewhat complicated by the (unwise) feature that allows "folding"
of header lines in the file: if a line starts with a space it should be
appended to the previous.
The previous code trimmed spurious CR characters wherever they would
occur in a line but this version does not. It does not seem like
something we want or that users would expect.
Test 646 uses this feature.

- tool_formparse: replace truncated `fseek` with `curlx_fseek`.
- tool_operate: replace truncated `fseek` with `curlx_fseek`.
- tool_paramhlp: replace local duplicate `myfseek`, with `curlx_fseek`.

Before this patch system `malloc()`/`free()` were used to allocate
the buffer returned in the `output_token` object from the debug stub
of `gss_init_sec_context()` when enabled via `CURL_STUB_GSS_CREDS` in
debug-enabled libcurl builds. This object is later released via stock
`gss_release_buffer()`, which, in the Windows builds of MIT Kerberos,
doesn't use the system `free()`, but the Win32 `HeapFree()`.
Fix it by using the GSS alloc/free macros: `gssalloc_malloc()` and
`gssalloc_free()` from `gssapi_alloc.h`.
To make this work without MIT Kerberos feature detection, use a canary
macro to detect a version which installs `gssapi_alloc.h` for Windows.
For <1.15 (2016-11-30) releases, that do not install it, disable the GSS
debug stub in libcurl.
Strictly speaking, non-Windows builds would also need to use GSS
allocators, but, detecting support for `gssapi_alloc.h` is impossible
without build-level logic. Built-level logic is complex and overkill,
and MIT Kerberos, as of 1.22.1, uses standard malloc/free on
non-Windows platforms anyway. (except in GSS debug builds.)

For files with sizes using an exact multiple of 256 bytes, the final
successful read(s) filled the buffer(s) and the subsequent fread
returned 0 for EOF, which caused read_file_into to fail.
Now, it needs to return 0 and not be EOF to be an error.

A bit more minimal build than the one used for trurl. To stress test
a build with most features disabled.
Costs 40 seconds, of which 6 is the build, rest is installing tools.

The choice to continue processing incoming data although the
writeout of the headers/data failed is not obvious. Add a comment
explaining why this is done.
Closes#19093
In MOST protocols and runs, the 'pretransfer' time is less than the
'starttransfer'. E.g. request being sent before response comes in.
However, when curl is starved of cpu a server response might start
streaming in before the multi-state transitioned to DID (and recorded
the 'pretransfer' time).
Do no longer check that 'pretransfer' is less or equal 'starttransfer'.
Check that is is less or equal to the total time instead.
Closes#19096
It's complex and did not help stabilizing CI runs.
Hard to say, but I'm suspicious it's related to the CI errors

'disk space used' steps.
