Add a new command-line switch `-x', which manipulates the
%load-extensions list.
* libguile/script.c (scm_compile_shell_switches): Process the new "-x"
switch.
(scm_shell_usage): Mention the "-x" switch.
* doc/ref/scheme-scripts.texi (Invoking Guile): Add "-x" switch to the
list of command-line switches.

* module/srfi/srfi-45.scm: New file, containing the reference implementation of
SRFI 45, slightly adapted to use SRFI-9.
* module/Makefile.am (SRFI_SOURCES): Added srfi/srfi-45.scm.
* test-suite/tests/srfi-45.test: New file.
* test-suite/Makefile.am (SCM_TESTS): Add tests/srfi-45.test.
* doc/ref/srfi-modules.texi (SRFI-45): New node and subsection;
essentially a shortended transcript of the SRFI-45 specification.
* module/srfi/srfi-42/ec.scm: New file; reference implementation of
SRFI 42.
* module/srfi/srfi-42.scm: New file; module for SRFI 42.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-42.scm.
(NOCOMP_SOURCES): Add srfi/srfi-42/ec.scm.
* test-suite/tests/srfi-42.test: New file; test suite for SRFI 42.
* test-suite/Makefile.am: SCM_TESTS: Add tests/srfi-42.test.
* module/srfi/srfi-27.scm: New file; implementation of SRFI 27 in terms
of the existing random number generator.
* module/Makefile.am (SRFI_SOURCES): Add srfi/srfi-27.scm.
* test-suite/tests/srfi-27.test: New file; minimal test suite for SRFI 27.
* test-suite/Makefile.am (SCM_TESTS): Add tests/srfi-27.test.
* doc/ref/srfi-modules.texi: Add subsection on SRFI-27 based
on the specification.
Now the random number generator state can be obtained in external
(i.e. `read'/`write'-able) form via the new procedure
`random-state->external'. An externalized state can be reinstantiated by
calling `external->random-state'.
* libguile/random.c (scm_i_init_rstate_scm, scm_i_expose_rstate): New
internal functions.
* libguile/random.c (scm_c_make_rstate_scm, scm_external_to_random_state,
scm_random_state_to_external): New public functions.
* libguile/random.h: Add prototypes for the above functions.
* libguile/random.h (scm_t_rng): Add new fields `init_rstate_scm' and
`expose_rstate'.
* libguile/random.c (scm_init_random): Initialize the new fields in
`scm_the_rng'.
