C backtrace tweaks.

Rename the environment variable that triggers the backtrace before
warns and croaks as PERL_USE_C_BACKTRACE_ON_ERROR (and correspondingly,
the define as USE_C_BACKTRACE_ON_ERROR).

Pod cleanups and updates, and move the needed #includes from perl.h
to util.c since that's the only place where they are needed.
perl.h
pod/perlhacktips.pod
util.c
