If HTTPAUTH_GSSNEGOTIATE was used for a POST request and
gss_init_sec_context() failed, the POST request was sent
with empty body. This commit also restores the original
behavior of `curl --fail --negotiate`, which was changed
by commit 6c60355323.
Add regression tests 2077 and 2078 to cover this.

It was used (intended) to pass in the size of the 'socks' array that is

the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries
that should be used instead.

- In curl_easy_reset attempt to resize the receive buffer to its default
size. If realloc fails then continue using the previous size.
Prior to this change curl_easy_reset did not properly handle resetting
the receive buffer (data->state.buffer). It reset the variable holding
its size (data->set.buffer_size) to the default size (READBUFFER_SIZE)
but then did not actually resize the buffer. If a user resized the
buffer by using CURLOPT_BUFFERSIZE to set the size smaller than the
default, later called curl_easy_reset and attempted to reuse the handle
then a heap overflow would very likely occur during that handle's next
transfer.

Several reasons:
- we can't add everyone who's helping out so its unfair to just a few
selected ones.
- we already list all helpers in THANKS and in RELEASE-NOTES for each
release
- we don't want to give the impression that some parts of the code is
"owned" or "controlled" by specific persons

PK11_IsPresent() checks for the token for the given slot is available,
and sets needlogin flags for the PK11_Authenticate() call. Should it

All protocols except for CURLPROTO_FILE/CURLPROTO_SMB and their TLS
counterpart were allowed for redirect. This vastly broadens the
exploitation surface in case of a vulnerability such as SSRF [1], where
libcurl-based clients are forced to make requests to arbitrary hosts.
For instance, CURLPROTO_GOPHER can be used to smuggle any TCP-based
protocol by URL-encoding a payload in the URI. Gopher will open a TCP
connection and send the payload.
Only HTTP/HTTPS and FTP are allowed. All other protocols have to be
explicitly enabled for redirects through CURLOPT_REDIR_PROTOCOLS.

There were a leftover few prototypes of Curl_ functions that we used to
export but no longer do, this removes those prototypes and cleans up any
comments still referring to them.
Curl_write32_le(), Curl_strcpy_url(), Curl_strlen_url(), Curl_up_free()
Curl_concat_url(), Curl_detach_connnection(), Curl_http_setup_conn()
were made static in 05b100aee2.
Curl_http_perhapsrewind() made static in 574aecee20.
For the remainder, I didn't trawl the Git logs hard enough to capture
their exact time of deletion, but they were all gone: Curl_splayprint(),
Curl_http2_send_request(), Curl_global_host_cache_dtor(),
Curl_scan_cache_used(), Curl_hostcache_destroy(), Curl_second_connect(),
Curl_http_auth_stage() and Curl_close_connections().

The file suffix for dynamically loadable objects on macOS is .dylib,

The value of the maxPTDs parameter to PR_Init() has since at least
NSPR 2.1, which was released sometime in 1998, been marked ignored
as is accordingly not used in the initialization code. Setting it
to a value when calling PR_Init() is thus benign, but indicates an
intent which may be misleading. Reset the value to zero to improve
clarity.
Closes https://github.com/curl/curl/pull/4054
Change the logic around such that we only keep CRLs that NSS actually
ended up caching around for later deletion. If CERT_CacheCRL() fails
then there is little point in delaying the freeing of the CRL as it

Some editors and IDEs assume that source files use UTF-8 file encodings.
It also fixes the build with MSVC when /utf-8 command line option is

is useful when using the same options is desired for building all
libraries of a project).

The header buffer size calculation can from static analysis seem to
overlow as it performs an addition between two size_t variables and
stores the result in a size_t variable. Overflow is however guarded
against elsewhere since the input to the addition is regulated by
the maximum read buffer size. Clarify this with a comment since the
question was asked.
