Update version to distinguish from release
test-basic: remove outdated configuration flag
close #3: add libc support
Rename internal include file in preparation for autoconf support
Move configuration options into EMBTEXTF namespace

Done in preparation for making <embtextf/config.h> something a user can
include to detect feature availability.
close #2 use autoconf

Use autoconf so the configure infrastructure can create a header and make
structure supporting the various feature options including the libc
wrappers.  This won't support the TI compiler, but will work with GCC.
Reformat
integrate Doxygen into autoconf support

Leverages the autoconf macros by Oren Ben-Kiki from
http://www.gnu.org/software/autoconf-archive/ax_prog_doxygen.html
Extend documentation to cover installation
add pkgconfig support

This might provide a clue to folks who need to know what flags are necessary
to compile and link programs that depend on embtextf.
Add -Wall -Werror for GCC builds
Fix up libc provide infrastructure

EMBTEXTF_ENABLE_PROVIDE_LIBC is redundant; use EMBTEXTF_PROVIDE_LIBC.
Document need to include separate library to get access to these functions,
since they technically belong to the compiler toolchain and some
applications might want to use the toolchain versions while still using
embtextf for other purposes.
Add Code Composer Studio support

Really crude, but it does seem to work.
Update version number for release
