Hartmut Brandt 5c86e3c106 Factor out all the .SHELL parsing related stuff into its own file and
rename the function to be consistent with the naming scheme in the rest
of make. No functional changes.

# Directive and keyword tables. We use hash tables. These hash tables have been
# generated with mph which can be found on the usual GNU mirrors.
# If you change the directives or keywords (adding, deleting, reordering) you
# need to create new tables and hash functions (directive_hash, keyword_hash).
#
# The following changes have been made to the generated code:
#
# o prefix the names of the g, T0 and T1 arrays with 'directive_'
# resp. 'keyword_'.
#
# o make the type of the tables 'const [un]signed char' (if you change
# anything make sure that the numbers fit into a char).
#
# o make the hash function use the length for termination,
# not the trailing '\0', via the -l flag in emitc and some editing
# (only for directive_hash).
