To avoid collision risks with private libcurl symbols when linked with
static versions (or just versions not hiding internal symbols).

- Change tool_util.c tvnow() for Windows to match more closely to
timeval.c Curl_now().
- Create a win32 init function for the tool, since some initialization
is required for the tvnow() changes.
Prior to this change the monotonic time function used by curl in Windows
was determined at build-time and not runtime. That was a problem because
when curl was built targeted for compatibility with old versions of
Windows (eg _WIN32_WINNT < 0x0600) it would use GetTickCount which wraps
every 49.7 days that Windows has been running.
This change makes curl behave similar to libcurl's tvnow function, which
determines at runtime whether the OS is Vista+ and if so calls
QueryPerformanceCounter instead. (Note QueryPerformanceCounter is used
because it has higher resolution than the more obvious candidate
GetTickCount64). The changes to tvnow are basically a copy and paste but
the types in some cases are different.

MinGW-w64 defaults to targeting Windows 7 now, so GetTickCount64 is
used and the milliseconds are represented as unsigned long long,
leading to a compiler warning when implicitly converting them to long.
Classic MinGW has neither InitializeCriticalSectionEx nor
GetTickCount64, independent of the target Windows version.

NOTICE: The list of 2 files that have been modified by other
intermixed commits, while renamed, and also by at least one
of the 6 commits this one reverts follows below. These 2 files
will exhibit a hole in history unless git's '--follow' option
is used when viewing logs.
lib/curl_imap.h
lib/curl_smtp.h
Configuration files such as curl_config.h and all config-*.h no longer exist
nor are generated/copied into 'src' directory, now these only exist in 'lib'
directory from where curl tool sources uses them.
Additionally old src/setup.h has been refactored into src/tool_setup.h which
now pulls lib/setup.h
The possibility of a makefile needing an include path adjustment exists.
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.
