new eclass: ccc

Hey list, this probably isnt of much interest to non-alpha users, but i've 
just committed a new eclass with functions to help make ccc compatability 
easier, theres a synopsis below.

#
#### hide-restrict-arr ####
# Scan for and replace __restrict_arr with a ccc
# supported equivalent.
#
# you might see an error like this if you need this:
# 
# cc: Error: regexec.c, line 209: In the definition of the function "regexec", 
# the promoted type of pmatch is incompatible with the type of the corresponding 
# parameter in a prior declaration. (promotmatch)
#     regmatch_t pmatch[];
#     ---------------^
#
#### replace-cc-hardcode ####
# Look for common cc hardcodes in Makefiles.
#
#### replace-cxx-hardcode ####
# Look for common cxx hardcodes in Makefiles.
#
#### is-ccc ####
# Returns success if dec compiler is being used.
#
# example:
#
# is-ccc && hide-restrict-arr
# 
#### is-cxx ####
# Returns success if dec c++ compiler is being used.
#
#### replace-ccc-g ####
# Try to replace -g with -g3 
#
#### ccc-elf-check </path/to/binary> ####
# Return success if binary was compiled with ccc
#
# example:
# if ! is-ccc; then
# ccc-elf-check /usr/lib/libglib.a && \
# append-ldflags -lots
# fi
#
# NOTE: i think the binary and shared library detection
# is pretty safe, but the archive detection may not
# be as reliable.
#### create-so </usr/lib/library.a> <library.so> ####
# Make the shared library (.so) specified from the archive (.a) 
# specified. LDFLAGS will be honoured. if you need a different 
# `soname` (DT_SONAME) from the shared lib filename, you will have 
# to do it manually ;)
#
# example:
# is-ccc && \
# create-so /usr/lib/libcoolstuff.a libcoolstuff.so.${PV}
# dosym /usr/lib/libcoolstuff.so.${PV} /usr/lib/libcoolstuff.so
#
# NOTE: -lots will be used by default, this is ccc.eclass after all :)
# NOTE: .${PV} is optional, of course.
# NOTE: dolib.so will manage installation
#### append-ldflags <flag> ####
#### is-ldflag <flag> ####
#### filter-ldflags <flag> ####
# flag-o-matic doesnt provide LDFLAGS utilities.
# Some replacements for ccc porting. These functions
# mimic the flag-o-matic equivalents, look in there for
# documentation.
