Symbols for both arm and x86.
+ missing declarations for getpwnam_r and getpwuid_r which were implemented
in Android 4.0.1. This didn't appear in previous comparison because the
platform header always declare these in <pwd.h>, so it never changed
when the functions were added. They appear in libc.so.functions.txt though.
The arm symbols are generated from the library files extracted from the
'yakju' platform build for 4.0.1 a.k.a. ITL41D.
The x86 symbols are generated by building the corresponding libraries
for the full_x86-eng product, using the same Bionic sources.
+ x86: Add missing symbols for "siglongjmp" and "sigsetjmp" which are not
exported by the gingerbread version of full_x86-eng libc.so. This was
checked with a fresh build of the product from the current gingerbread
tree on the AOSP server. Probably a bug, but a minor one.
