With bug 1077366, the linker makes the library containing it a fake
LD_PRELOAD. As a consequence, instead of, in the linker itself,
explicitely special-casing the symbols that disappeared in Android 4.4
that the flash plugin uses, it is now possible to use normal symbol
resolution to stubs defined separately in libmozglue.
Since essentially everything is linked to libmozglue and libmozglue takes
precedence in symbol resolution in our dynamic linker, there is no need
to wrap most symbols. PR_GetEnv/PR_SetEnv still needs wrapping because
there's no other way to actually wrap the calls from NSPR itself and NSS,
as well as the symbols wrapped because our dynamic linker can't find them
in system libraries on some devices because they're weak.

Need to reimplement PR_GetEnv and PR_SetEnv so that we can access
to the lock. This is needed by PR_DuplicateEnvironment, which
was moved to ipc/chromium/src/base/process_util_linux.cc otherwise
the alloc/frees don't get matched up properly.
This is tempoarary until we can get PR_DuplicateEnvironment landed
into NSPR.

This is a hacked up version of PR_DuplicateEnvironment which
we can use until such time as we can get a version landed in
NPSR
