Compiling with msvc /analyze and a recent Windows SDK warns against
using GetTickCount (Suggests to use GetTickCount64 instead.)
Since GetTickCount is only being used when GetTickCount64 isn't
available, I am disabling that warning.

- Use QueryPerformanceCounter on Windows Vista+
There is confusing info floating around that QueryPerformanceCounter
can leap etc, which might have been true long time ago, but no longer
the case nowadays (perhaps starting from WinXP?). Also, boost and
std::chrono::steady_clock use QueryPerformanceCounter in a similar way.
Prior to this change GetTickCount or GetTickCount64 was used, which has
lower resolution. That is still the case for <= XP.

Classic MinGW has neither InitializeCriticalSectionEx nor
GetTickCount64, independent of the target Windows version.

... since the 'tv' stood for timeval and this function does not return a
timeval struct anymore.
Also, cleaned up the Curl_timediff*() functions to avoid typecasts and
clean up the descriptive comments.
Closes#2011
... to cater for systems with unsigned time_t variables.
- Renamed the functions to curlx_timediff and Curl_timediff_us.
- Added overflow protection for both of them in either direction for
both 32 bit and 64 bit time_ts
- Reprefixed the curlx_time functions to use Curl_*

... 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.
Ref: #1652Closes#1693
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.

This gives us accurate precision and it allows us to avoid storing "no
time" for systems with too low timer resolution as we then bump the time
up to 1 microsecond. Should fix test 573 on windows.
Remove the now unused curlx_tvdiff_secs() function.
Maintains the external getinfo() API with using doubles.
Fixes#1531
There is an issue with conflicting "struct timeval" definitions with
certain AmigaOS releases and C libraries, depending on what gets
included when. It's a minor difference - the OS one is unsigned,
whereas the common structure has signed elements. If the OS one ends up
getting defined, this causes a timing calculation error in curl.
It's easy enough to resolve this at the curl end, by casting the
potentially errorneous calculation to a signed long.
Updated the usage of some legacy APIs, that are preventing curl from
compiling for Windows Store and Windows Phone build targets.

Skip a floating point addition operation when integral part of time difference
is zero. This avoids potential floating point addition rounding problems while
preserving decimal part value.
when function clock_gettime() is available and the monotonic timer is
also available. Otherwise, in some cases, librt or libposix4 could be used
for linking even when finally not using the clock_gettime() function due
to lack of the monotonic clock.
