djsollen b2a6fe7976 Enable both static and dynamically linked libpng
All platforms except android are configured to use the statically linked copy
of libpng. Android uses the system provided dynamic copy for SkImageDecoder
and the static copy for SkCodec. The exception being android framework builds
that currently use the dynamic copy everywhere.

This CL also enables NEON optimizations for libpng.

# Get ready for the ugly...
#
# - We have to nest our variables dictionaries multiple levels deep, so that
# this and other gyp files can rely on previously-set variable values in
# their 'variables': { 'conditions': [] } clauses.
#
# Example 1:
# Within this file, we use the value of variable 'skia_os' to set the
# value of variable 'os_posix', so 'skia_os' must be defined within a
# "more inner" (enclosed) scope than 'os_posix'.
#
# Example 2:
# http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libjpeg/libjpeg.gyp?revision=102306 ,
# which we currently import into our build, uses the value of 'os_posix'
# within the 'conditions' list in its 'variables' dict.
# In order for that to work, it needs the value of 'os_posix' to have been
# set within a "more inner" (enclosed) scope than its own 'variables' dict.
#
# - On the other hand, key/value pairs of a given 'variable' dict are only
# inherited by:
# 1. directly enclosing 'variable' dicts, and
# 2. "sibling" 'variable' dicts (which, I guess, are combined into a single
# 'variable' dict during gyp processing)
# and NOT inherited by "uncles" (siblings of directly enclosing 'variable'
# dicts), so we have to re-define every variable at every enclosure level
# within our ridiculous matryoshka doll of 'variable' dicts. That's why
# we have variable definitions like this: 'skia_os%': '<(skia_os)',
#
# See http://src.chromium.org/viewvc/chrome/trunk/src/build/common.gypi?revision=127004 ,
# which deals with these same constraints in a similar manner.
