c95c0c9725 modified util::time API 
for easier invocation.
- no longer expose frequency timer :
it's either useless, or stored internally in a static variable (init is only necessary once).
- UTIL_getTime() provides result by function return.

6ab4d5e904 [bench] Use higher resolution timer on POSIX 
The timer used was only accurate up to 0.01 seconds. This timer is accurate up to 1 ns.
It is a monotonic timer that measures the real time difference, not on CPU time.

3306bcb0e6 fix #820 : GCC v3.x 32-bits doesn't define 64-bits intrinsic 
resulting in undefined symbol error.
Push the requirement to GCC 4 for now.
Another solution, proposed by @NWilson, is to use __LONG_MAX__ instead.
__LONG_MAX__ is a GCC-specific constant, which value is supposed to depend on underlying target hardware (32/64 bits)
Might be better, but seems also more complex, hence more prone to side effects.
Keeping the simple solution for now (just rely on __GNUC__)

b3f33ccfb3 use ZSTD_decodingBufferSize_min() inside ZSTD_decompressStream() 
Use same definition as public one
minor : reduce allocated buffer size in some cases
(when frameContentSize is known and == windowSize)

058ed2ad33 ZSTD_decodingBufferSize_min() 
supporting function for bufferless streaming API (ZSTD_decompressContinue())
makes it possible to correctly size a round buffer for decoding using this API.

also : added field blockSizeMax within ZSTD_frameHeader,
as it's a necessary information to know when to restart at beginning of decoding buffer.
