a7cc0b590a Fix make install 
* Uninstall didn't remove the pkg-config correctly.
* Fix `mandir`
* Allow overriding either upper- or lower-case location variables, but
  always use the lower case variables.
* Add test case that ensures overriding both upper- and lower-case
  variables is the same, and that the directory is empty after uninstall.

5a2501a90d added a test case for LZ4_decompress_fast_usingDict 
with a separated dictionary
since a joined dictionary is now detected as prefix64K.

Also : fixed a minor warning under msys

133a50b780 fixed DISPLAYUPDATE() 
wrong comparison, which was always overflowing (hence was always true)
except when it was not (i386, reported by pmc)
in which case it would never show any information.

ae3dededed ensure bench speed measurement is more accurate for small inputs 
Previous method would produce too many time() invocations,
becoming a significant fraction of workload measured.

The new strategy is to use time() only once per batch,
and dynamically resize batch size so that each round lasts approximately 1 second.

This only matters for small inputs.
Measurement for large files (such as silesia.tar) are much less impacted
(though decoding speed is so fast that even medium-size files will notice an improvement).

74d8688bc8 [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.

01cdbfb5fe lz4c legacy commands are now enabled at runtime based on link/binary name "lz4c" 
instead of selected at compilation time depending on a macro.
This design makes it possible to have a single binary which supports both modes.

An advantageous side effect is that when doing `make; make install`
no additional binary is created during `make install`
(it used to create `lz4c`, because `make` would only build `lz4`)
