The operators set, inc, dec, pop and others are now macros
which generate code, rather than built-in special forms
that use "C magic". Moreover, new such macros are easy to write, and
several new ones are already available. Moreover, new kinds of
assignable places are easy to create.
* place.tl: New file.
* lisplib.c, lisplib.h: New files.
* Makefile (OBJS): New target, lisplib.o.
(GEN_HDRS): New variable.
(LISP_TO_C_STRING): New recipe macro, with rule.
(clean): Remove generated headers named in $(GEN_HDRS).
* eval.c (dec_s, push_s, pop_s, flip_s, del_s): Variables removed.
(setq_s): New variable.
(lookup_var, lokup_sym_lisp_1, lookup_var_l, lookup_fun, lookup_mac,
lookup_symac, lookup_symac_lisp1): Trigger the delayed loading of
libraries for undefined global symbols, and re-try the lookup.
(op_modplace, dwim_loc, force_l): Static functions removed.
(op_setq): New static function.
(eval_init): Initialize setq_s; remove initializations of
removed variables; remove registrations for op_modplace;
add registration for sys:setq, sys:rplaca, sys:rplacd,
sys:dwim-set and sys:dwim-del intrinsics.
Call lisplib_init to initialize the dynamic library loading module.
* lib.c (sys_rplaca, sys_rplacd): New functions, differing
in return value from rplaca and rplacd.
(ref, refset): Handle hash table.
(dwim_set, dwim_del): New functions.
* lib.h (sys_rplaca, sys_rplacd, dwim_set, dwim_del): Declared.
* genvim.txr: Include place.tl in scan.
* tests/010/seq.txr: The del operator test
case no longer throws at run-time but at macro-expansion time, so the
test case is simply removed.
* tests/010/seq.expected: Updated output.
* tests/011/macros-2.txr: Reset *gensym-counter* to zero, because
the textual output of the test case includes gensyms, whose numberings
fluctuate with the content of the new Lisp library material.
* tests/011/macros-2.expected: Updated output.

of identifiers to rule this out from being the first character of a
symbol which has no prefix. Recognize the ^ character as a token in the
NESTED state.
* lib.c (obj_print, obj_pprint): Render sys:qquote as ^.
* parser.y (choose_quote): Function removed.
(n_expr): Recognize '^' as quasiquote. Removed all the "smart quote"
hacks that try to make quote behave as quote or quasiquote, or try to
cancel out unquotes and quotes.
* tests/009/json.txr: Fixed to ^ quasiquote.
* tests/010/reghash.txr: Likewise.
* tests/011/macros-2.txr: Likewise.
* tests/011/mandel.txr: Likewise.
* tests/011/special-1.txr: Likewise.
* txr.1: Updated docs.
* genvim.txr: Revamped definitions for txr_ident and txl_ident so that
unqualified identifiers cannot start with # or ^, but ones with @ or :
in front can start with these characters.
* txr.vim: Regenerated.

function. This must not flush out more than one character out of this
small buffer, except when we are flushing out the last data.
The correct operation is predicated on the assumption that
a complete character can be pulled out. That's why we move the
buffer to the front after consuming it, and do not automatically
flush until there are four bytes.
(string_out_put_string): We loop the call to string_out_byte_flush
here because when a request comes in to write a Unicode character,
we flush all the bytes, even if the tail of those bytes forms
an incomplete sequence that turns into U+DCxx codes.
(get_string_from_stream): Use the same loop termination test
as in string_out_put_string, for consistency. In that function
it is needed to prevent infinite looping in the case when
the string_out_put_string is being called from string_out_byte_flush
and is thus re-entering it.
* tests/010/strstream.expected: New file.
* tests/010/strstream.txr: New file.
