* module/web/server.scm (call-with-encoded-output-string): Fix some code
I accidentally left in while testing. Re-tested the difference in
speed; pleasantly surprised.
* module/web/uri.scm: Make the same change here.
* module/system/foreign.scm: Revert much of fb636a1cce. Short et al are
not distinct types -- they are all aliases to e.g. int16. The only
case that was not covered before was the pointer case.
(bytevector-pointer-ref, bytevector-pointer-set!): Implement these,
and use them for pointers.
* module/web/uri.scm (call-with-encoded-output-string, encode-string):
Copy from server.scm
(decode-string): Copy from tekuti.
(uri-decode): The #:charset arg is a string, like
port-encoding. Support other charsets.
(uri-encode): Charset is a string. Other encodings still not nicely
supported. Hmm.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Don't emit
a self-label, because when we can't match the args for a lexical call,
we have no space to shuffle args and jump.
(flatten): Apply the self-tail-call optimization to optional args
too, but only if the procedure is fix-allocated. If we can't apply the
optimization, use the normal tail-call sequence.
* test-suite/tests/optargs.test ("lambda* inits"): Add tests.
* module/language/tree-il/compile-glil.scm (vars->bind-list, flatten):
Make internal self-checking error messages more clear, for
implementors of other languages.
* module/srfi/srfi-26.scm (cut, cute): Implement using `syntax-case'.
The new implementation is mostly just a transcription of the old code;
the reference implementation which relies only on `syntax-rules' may
(or may not) be considered more elegant :-).

Use #{`}#, #{,}# and #{,@}# as the quasiquote, unquote and
unquote-splicing operators, respectively. Previously they were named
escaping.
* module/language/elisp/compile-tree-il.scm (unquote?): Change "\," to
"#{,}#".
(unquote-splicing): Change "\,@" to "#{,@}#".
(#{compile-`}#): Rename from #{compile-\`}#.
* module/language/elisp/runtime/function-slot.scm: Import #{compile-`}#
instead of #{compile-\`}#, and re-export as #{`}# instead of as
#{\`}#.

"\,@" to "#{`}#", "#{,}#" and "#{,@}#", respectively.
If the function slot of a symbol contains a pair with `special-operator'
in the car and a procedure in the cdr, the procedure is called to
compile the form to Tree-IL. This is similar to other Emacs Lisp
implementations, in which special operators are subrs.
* module/language/elisp/compile-tree-il.scm: Restructured to store
special operator definitions in the function slot. Import `(language
elisp runtime)' for `defspecial'. Export special operators so that
`(language elisp runtime function-slot)' can re-export them.
(backquote?): Removed; the backquote symbol is defined as a special
operator, so it's no longer used in `compile-pair'.
(is-macro?, get-macro): Replaced by `find-operator'.
(find-operator): New procedure.

compile-quote): New special operators with definitions taken from the
pmatch form in `compile-pair'. There is no special operator `lambda';
it is now a macro, as in other Elisp implementations.
(compile-pair): Instead of directly compiling special forms, check for
a special operator object in the function slot.
* module/language/elisp/runtime.scm: Export `defspecial'.

Guile Emacs Lisp previously kept macros in a separate macro slot; now
macros are stored as macro objects in the function slot for
compatibility with other implementations.
* module/language/elisp/compile-tree-il.scm (macro-slot): Remove.
(is-macro?): Check that the argument is a symbol. Now-unnecessary
check removed in `compile-tree-il'.
(macro?, define-macro!, get-macro): Store macro definitions in the

function in a macro object (i.e., cons the symbol `macro' onto it).
* module/language/elisp/runtime/function-slot.scm: Move contents to

Throw an error if not invoked as `guile-test'.
(test-suite): The old default value of `default-test-suite' could now
throw an error, and this already gets initialized in `main', so don't
provide an initial value.

* module/web/server/http.scm (http-read): Don't play the setvbuf dance,
it was throwing away buffered input. Instead just call setvbuf once
before doing any reads or writes.
