thrreads::shared: LEAVE in BOOT had wrong context

In Perl_sharedsv_init() - which is called from the threads::shared BOOT
code - it creates a new shared interpreter, then tries to undo the ENTER
done as the last step of the perl_construct(PL_sharedsv_space) step, with
a LEAVE. But the LEAVE was being done in the context of the caller
interpreter rather than the shared one.

rename sTHX to PERL_MEMORY_DEBUG_HEADER_SIZE

Originally this macro evaluated to the size of the THX pointer;
this was used with the memory pool facility to store the context of the
caller of the malloc() for debugging. Later, the header of the malloc()
stored more than just the context, so sTHX became a mismoner.

Rename it to something less misleading.

   [BUGFIXES]
   * Fix unweaken() for perls < 5.14; need to use sv_setsv() to undef
     rather than sv_clear() (RT92226)
sv.c, Perl_dirp_dup: Skip the fchdir sections if telldir and seekdir are not defined
Hints file for android cross-compiling.

The hints file names for cross-compiling (currently) need to match the prefix of the cross-compiler used.
Create a Perl with relocatable inc when building for Android.
Android hints: set targetsh to /system/bin/sh

Android, for reasons best known to itself, doesn't have a "/bin/sh" it
has a "/system/bin/sh".  We need to run "/bin/sh" as $sh inside
./Configure on the host, but store a different path for use on the
actual Android system (eg by backticks, system etc, in SH_PATH).

The new variable is "targetsh" and defaults to "sh" unless changed by the hints file/Configure params.
Android hints, run-adb-shell: Handle the -env switch

Currently, this is used during 'make test' to specify LD_LIBRARY_PATH
No locales in Android, just set the lot to undef
Android hints, run-ssh: Make sure that the stdout of commands run from Configure and Makefile on remote hosts is transfered back correctly
