Major layout change to the packages directory

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.

The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.

Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.

++dnl @synopsis ACX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
++dnl
++dnl This macro figures out how to build C programs using POSIX threads.
++dnl It sets the PTHREAD_LIBS output variable to the threads library and
++dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
++dnl C compiler flags that are needed. (The user can also force certain
++dnl compiler flags/libs to be tested by setting these environment
++dnl variables.)
++dnl
++dnl Also sets PTHREAD_CC to any special C compiler that is needed for
++dnl multi-threaded programs (defaults to the value of CC otherwise).
++dnl (This is necessary on AIX to use the special cc_r compiler alias.)
++dnl
++dnl NOTE: You are assumed to not only compile your program with these
++dnl flags, but also link it with them as well. e.g. you should link
++dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
++dnl $LIBS
++dnl
++dnl If you are only building threads programs, you may wish to use
++dnl these variables in your default LIBS, CFLAGS, and CC:
++dnl
++dnl        LIBS="$PTHREAD_LIBS $LIBS"
++dnl        CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
++dnl        CC="$PTHREAD_CC"
++dnl
++dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
++dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
++dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
++dnl
++dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
++dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
++dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
++dnl default action will define HAVE_PTHREAD.
++dnl
++dnl Please let the authors know if this macro fails on any platform, or
++dnl if you have any other suggestions or comments. This macro was based
++dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
++dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
++dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
++dnl We are also grateful for the helpful feedback of numerous users.
