Make the number parser aware of the maximum limit curl accepts for a
value and return an error immediately if larger, instead of running an
integer overflow later.

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

This breaks the darwinssl build on Travis. Fix it by making this token
a comment.

When using CURL_WERROR in MSVC builds, the debug flags were overridden
by the release flags and /WX got added twice in debug mode.

This makes the builds more reproducible as travis is currently rolling
out trusty as default dist [1]. Specifically, this avoids coverage
check failures when trusty is used as seen in [2] until we figure out
what's wrong.

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.

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).
