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.

c25eb16666 random lz4f clarifications 
the initial intention was to update lz4f ring buffer strategy,
but lz4f doesn't use ring buffer.
Instead, it uses the destination buffer as much as possible,
and merely copies just what's required to preserve history
into its own buffer, at the end.
Pretty efficient.

This patch just clarifies a few comments and add some assert().
It's built on top of #528.

It also updates doc.

69242a8a08 lib/Makefile: show commands with V=1 
`make V=1` will now show the commands executed to build the library.
A similar technique is used in e.g. linux/Makefile.

The bulk of this change is produced with the following vim command:

    :g!/^\t@echo\>/s/^\t@/\t\$(Q)/

d81a434c3d lz4.c: fixed the LZ4_decompress_fast_continue case 
The change is very similar to that of the LZ4_decompress_safe_continue
case.  The only reason a make this a separate change is to ensure that
the fuzzer, after it's been enhanced, can detect the flaw in
LZ4_decompress_fast_continue, and that the change indeed fixes the flaw.

ce4e1389cc fuzzer.c: enabled ring buffer tests for decompress_fast 
Ring buffer tests were performed only with LZ4_decompress_safe_continue,
leaving my buggy changes to LZ4_decompress_safe_continue undetected.
The tests are now replicated and performed in a similar manner for both
LZ4_decompress_safe_continue and LZ4_decompress_safe_continue (except
for the small buffer case where only one function can be tested,
because part of the dictionary is overwritten with the output).

I also updated function names in the messages (changed them to the
actual ones).  The error was reported for LZ4_decompress_safe(),
which I found misleading.
