Fix 'pow' macros in pngvalid.c
...
It is legal for 'pow' to be a macro, therefore the argument list cannot contain
preprocessing directives. Make sure pow is a function where this happens (this
is a minimal safe fix, the issue only arises in non-performance-critical code.)

pngvalid.c is changed to drop this encoding in prior versions.

New test PNG files incorporated into make check
...
tests/pngstest-* are changed so that the new test files are divided into 8
groups by gamma and alpha channel. This makes each test take just under 5
seconds on a moderately up-to-date x86_64 system using libpng16 (test times are
somewhat variable under libpng17 at present because of the lack of optimization
in some gamma processing paths.)
These tests have considerably better code and pixel-value coverage than
contrib/pngsuite however coverage is still incomplete.

png_rgb_to_gray optimization fixes
...
This fixes the code that optimizes RGB to Gray transformations that only
selected on channel and clarifies the handling of max_depth in the transform
code. It eliminates some UNTESTED cases and removes the write 'invert alpha'
UNTESTED macro because, while there are no test cases for it, code review
some months after writing it suggests it is ok.
