CVE-2017-1000100
Bug: https://curl.haxx.se/docs/adv_20170809B.html

First: this function is only used in debug-builds and not in
release/real builds. It is used to drive tests using the event-based
API.
A pointer to the local struct is passed to CURLMOPT_TIMERDATA, but the
CURLMOPT_TIMERFUNCTION calback can in fact be called even after this
funtion returns, namely when curl_multi_remove_handle() is called.

When multiple rounds are needed to establish a security context
(usually ntlm), we overwrite old token with a new one without free.
Found by proposed gss tests using stub a gss implementation (by
valgrind error), though I have confirmed the leak with a real
gssapi implementation as well.

clang complains:
vtls/darwinssl.c:40:8: error: extra tokens at end of #endif directive
[-Werror,-Wextra-tokens]
This breaks the darwinssl build on Travis. Fix it by making this token
a comment.

The MSVC warning level defaults to 3 in CMake. Change it to 4, which is
consistent with the Visual Studio and NMake builds. Disable level 4
warning C4127 for the library and additionally C4306 for the test
servers to get a clean CURL_WERROR build as that warning is raised in
some macros in older Visual Studio versions.

Use LongToHandle to convert from long to HANDLE in the Win32
implementation.
This should fix the following warning when compiling with
MSVC 11 (2012) in 64-bit mode:
lib\curl_threads.c(113): warning C4306:
'type cast' : conversion from 'long' to 'HANDLE' of greater size
Closes https://github.com/curl/curl/pull/1717
There are some bugs in how timers are managed for a single easy handle
that causes the wrong "next timeout" value to be reported to the
application when a new minimum needs to be recomputed and that new
minimum should be an existing timer that isn't currently set for the
easy handle. When the application drives a set of easy handles via the
`curl_multi_socket_action()` API (for example), it gets told to wait the
wrong amount of time before the next call, which causes requests to
linger for a long time (or, it is my guess, possibly forever).

The headers of librtmp declare the socket as `int`, and on Windows, that
disagrees with curl_socket_t.

... to make all libcurl internals able to use the same data types for
the struct members. The timeval struct differs subtly on several
platforms so it makes it cumbersome to use everywhere.

This is a follow-up to af02162 which removed (SET_)ERRNO macros. That
commit was an earlier draft that I committed by mistake, which was then
remedied by a5834e5 and e909de6, and now this commit. With this commit
there is now no difference between the current code and the changes that
were approved in the final draft.

ldap_bind_s is marked as deprecated in w32api's winldap.h shipping with
the latest original MinGW, resulting in compiler warnings since commit
f0fe66f13c. Fix this for the non-SSPI
case by using ldap_simple_bind_s again instead of ldap_bind_s with
LDAP_AUTH_SIMPLE.
Closes https://github.com/curl/curl/pull/1664
Prior to this change (SET_)ERRNO mapped to GetLastError/SetLastError
for Win32 and regular errno otherwise.
I reviewed the code and found no justifiable reason for conflating errno
on WIN32 with GetLastError/SetLastError. All Win32 CRTs support errno,
and any Win32 multithreaded CRT supports thread-local errno.

GCC 4.6.3 on travis complains:
smb.c: In function ‘get_posix_time’:
smb.c:725:13: error: declaration of ‘time’ shadows a global declaration
[-Werror=shadow]
Fix this by renaming the variable.
On a 64 bit host, sparse says:
timeval.c:148:15: warning: constant 0x7fffffffffffffff is so big it is long
timeval.c:149:12: warning: constant 0x7fffffffffffffff is so big it is long
so let's use long long constant types in order to prevent undesired overflow
failures.

- Change gnutls pointer/int macros to pointer/curl_socket_t.
Prior to this change they used long type as well.
The size of the `long` data type can be shorter than that of pointer
types. This is the case most notably on Windows.
If C99 were acceptable, we could simply use `intptr_t` here. But we
want to retain C89 compatibility.
Simply use the trick of performing pointer arithmetic with the NULL
pointer: to convert an integer `i` to a pointer, simply take the
address of the `i`th element of a hypothetical character array
starting at address NULL. To convert back, simply cast the pointer
difference.
Thanks to Jay Satiro for the initial modification to use curl_socket_t
instead of int/long.

Add a new type of callback to Curl_handler which performs checks on
the connection. Alter RTSP so that it uses this callback to do its
own check on connection health.
Prevent `Curl_pgrsTime` from modifying `t_starttransfer` when invoked
with `TIMER_STARTTRANSFER` more than once during a single request.
When a redirect occurs, this is considered a new request and
`t_starttransfer` can be updated to reflect the `t_starttransfer` time
of the redirect request.

Bug: https://github.com/curl/curl/pull/1602#issuecomment-310267370
If libcurl was built with GSS-API support, it unconditionally advertised
GSS-API authentication while connecting to a SOCKS5 proxy. This caused
problems in environments with improperly configured Kerberos: a stock
libcurl failed to connect, despite libcurl built without GSS-API
connected fine using username and password.
This commit introduces the CURLOPT_SOCKS5_AUTH option to control the
allowed methods for SOCKS5 authentication at run time.
Note that a new option was preferred over reusing CURLOPT_PROXYAUTH
for compatibility reasons because the set of authentication methods
allowed by default was different for HTTP and SOCKS5 proxies.
