marked space.

opcodes.
This change to the expander allows mixed local definitions and
expressions. The expansion turns:
(let () (a) (define (b) 42) (b) (b))
into:
(let ()
(letrec* ((t0 (begin (a) (if #f #f)))
(b (lambda () 42)))
(b)))
Which is to say, expressions that precede definitions are expanded as
definitions of a temporary via (begin EXP (if #f #f)).

(define-module*, define-module): Add #:declarative? keyword argument,
defaulting to the value of user-modules-declarative? parameter when
the module was expanded.
(guile-user): This module is not declarative.

Use the new declarative? module flag.

shuffling return values, we need to reset the frame after any "extra"
values are read and before any "extra" values may be set.

variables. Assigned variables get a % sigil before them. Also, avoid
the mutable-error dance.
* module/language/tree-il/fix-letrec.scm (fix-scc): Initial binding of
letrec values is unspecified, not false.
* test-suite/tests/peval.test (pass-if-peval): Fix letrec before
pevalling. Update tests. A couple got better, no regressions.
* module/language/tree-il/optimize.scm (optimize): Change to run
fix-letrec before peval. Also, run it unconditionally, so that later
passes don't have to deal with letrec.
* module/language/tree-il/peval.scm (build-var-table, peval): Remove
letrec cases.
* module/language/tree-il/fix-letrec.scm: Update algorithm to use
approach from "Fixing Letrec (reloaded)", which sorts mutually
recursive bindings by using Tarjan's algorithm to partition the
bindings into strongly-connected components. The result is that users
can use letrec* or internal definitions and get a result that is as
efficient as manual placement of let / letrec.
Some components of this have been wired up for a while; this commit
finishes the compiler, runtime, and JIT support.

primitives.
This binding was forgotten when (ice-9 ports) was introduced in
44b3342c4d. Thus it has always been
missing in Guile 2.2.
* module/ice-9/ports.scm: Export 'current-load-port'.
These procedures were removed in Guile 2.2 by commit
fc7bd367ab (May 2011).
* libguile/socket.h (scm_inet_aton, scm_inet_ntoa): Remove.
* module/system/repl/server.scm (make-tcp-server-socket): Use
'inet-pton' instead of 'inet-aton'.

* doc/ref/posix.texi (Network Address Conversion): Remove documentation
of 'inet-ntoa' and 'inet-aton'.

and @math. The tags used come from the texinfo documentation.
(rules): Convert @tie and @dots to the appropriate HTML entities.
* module/web/http.scm (spaces-and-tabs, space-or-tab?): New variables.
(read-header-line): After reading a header, if a space or tab follows,
read the continuation lines and join them.

* module/ice-9/suspendable-ports.scm (get-bytevector-n!): New procedure.
(get-bytevector-n): Rewrite in terms of 'get-bytevector-n!'.

* doc/ref/r6rs.texi (rnrs io ports): Improve the descriptions of
'binary-port?' and 'textual-port?'.
* module/rnrs/io/ports.scm (binary-port?, textual-port?): Update the
docstrings.
