[0/3,RFC] Android fixes and -Werror-implicit-function-declaration as default

Hi,

patchset [1] from Zhengwang Ruan reminded me my old patchset, which I
haven't sent. Still not sure if all this hunting for 'implicitly
declaring library function' make sense. Maybe it'd be better just remove
-Werror-implicit-function-declaration for Android. Nevertheless this
patchset fixes most (or even all) of them enable
-Werror-implicit-function-declaration for all targets/platforms.

NOTE: this still don't fix Android build (with NDK compiler, outside AOSP
tree), but makes it closer (now it builds at least lib/ folder).

Kind regards,
Petr
