add very naive every-instruction tracing.... <lol>
Make tracing a build-time instead of configuration-time decision.

Instead of a configuration flag --tracing, there are now
build targets 'tracing' and 'no-tracing'.
Import modified f38b2904 of ivmai/libatomic_ops
beginnings of source code/repo documentation.. designed to be visible when browsing the source tree in github.
stub in serialization
Merge branch 'atomic'
Support noiseless building.

Pass NOISY=1 to make to see actual commands.
Fix build messages on GNU make
Add /nologo to nmake invocation
Take byte order from Perl's %Config.

In case of cross builds, use explicit --big-endian.

Conditional compilation now also consistently checkes for
definedness of MVM_BIGENDIAN.
Make MVMint8 a signed char - signedness of plain char is implementation-defined
Remove nonportable conditional commands from Makefile.in

Not all makes support conditional IF/ELSE/ENDIF statements.
Specifically, the /usr/bin/make supplied with Solaris 11 does not.
There is probably some more portable way to do what was intended,
but for now I'll just get rid of the problematic lines and move
on to other issues.
Fix mismatched types in sprintf in src/core/exceptions.c

MVM_string_utf8_encode returns an unsigned char pointer, but
the expression is expecting a signed char pointer.  gcc complains,
but continues anyway.  The Solaris compiler aborts.
This patch casts the MVM_string_utf8_encode return to (char *),
but somebody who understands the function might be better positioned
to understand whether the MVM function definition itself ought to
be changed instead.
Add build/setup.pm section for Solaris with Solaris cc.

This adds a generic 'cc' compiler type, intended as a workable
default if the user does not have gcc installed.  It also adds
Solaris-11 specific flags suitable for use with Solaris cc.
I have not tested other Solaris versions, nor have I tested
this with Solaris with gcc installed instead.
Avoid 'make -C'. Use a simple cd instead.

Not all 'make' variants support 'make -C dir' to change
directory.  GNU make, FreeBSD and NetBSD make do, but Solaris make
and OpenBSD make do not.  This commit simply changes directory
manually (and then changes back at the end for Windows, where
the cd is persistent).  A more portable version might do something
like parrot's make_c command.
Re-introduce quiet builds and NOISY make option.

Hopefully more portable now.
Only suppress stderr in quiet build mode
Start logic for shared libs as well as various cleanups
Add MVM_PUBLIC/MVM_PRIVATE with dummy condition for now
Auto-detect readline
