* share/txr/stdlib/place.tl: Introducing new defplace
for (sys:var ...) which is treated as if it were a symbol,
in anticipation of the op/do macro placing that syntax
with a symbol.

* parser.l (%option): Remove nounput option since we need
yyunput.
(grammar): Rule for matching hex and octal escape in SPECIAL
state recognizes optional semicolon. In 109 compatibility,
this is pushed back into the stream, otherwise consumed.
* txr.1: Updated documentation, including compat notes.
* genvim.txr (txr_char): Include optional semicolon in
match. Corrected some errors where 8 and 9 were being
included as matches for octal digits.
(txr_error): Default match for \x or \o not followed
by digits.

* parser.c (read_eval_stream): New boolean argument
to request hash bang support.
* parser.h (read_eval_stream): Declaration updated.
* eval.c (sys_load): Pass new thid argument to read_eval_stream,
to decline hash bang support.
* match.c (v_load): Likewise.
* txr.c (txr_main): Request hash bang support from
read_eval_stream. Thus files referenced from the txr
command line can have a #! line, which is ignored.

* genvim.txr (txr_badesc, txr_stresc, txr_numesc, txr_regesc): New
match categories.
(txr_string, txr_quasilit, txr_regex, txl_regex): No longer use skip=
argument, but rather contain escape categories.
All escapes are colored as Special rather than String, and
unknown or malformed escapes are colored as errors.

* genvim.txr (txr_escat): New match category containing \@.
Colorized a String.
(txr_quasilit): Contains txr_escat. Thus, \@ looks like any
other escape inside a quasilit.

* configure (have_timegm, tm_gmtoff, tm_tmzone): Unused
variables removed.
(SIZEOF_LONG_LONG_T): Reference to nonexistent variable fixed.
Also, fixed two instances of arithmetic expressions using
unnecessary $ prefixes on variables.

* eval.c (expand_quasi): When the modifiers argument of a var
item is expanded, the expansion incorrectly places it as the
fourth item rather than third. This is effectively a continuation
of the incomplete regression fix that was applied on 2014-08-29.
The breakage is that `@{(expr) modifier}` ignores modifier
whenever (expr) is an expression that undergoes expansion.

* parser.l (char_esc): Recognize \@ escape.
(grammar): Add a rule for a \@ escape in quasiliterals,
and quasi word list literals.
* txr.1: Document \@, and remove the lie that @@
encodes for a single @ in quasiliterals.

* parser.l (char_esc): Recognize \@ escape.
(grammar): Add a rule for a \@ escape in quasiliterals,
and quasi word list literals.

|
| |
* parser.l: Only shift to QSPECIAL state when @ is followed
by a trailing context consisting of certain characters.
Not every kind of Lisp object syntax can be introduced
with @ in a quasiliteral. Adding a rule to produce an
error when @ appears that is not followed by an allowed
character.

* parser.l: Do not try to recognize floating-point literals
in QSPECIAL state; that is not possible because @134.3
in a quasiliteral parses as a METANUM followed by ".3".
On the other hand, recognize METANUM literals in QSPECIAL state,
so that @@123 scans. Recognize @ as a token in QSPECIAL state,
so @@abc will scan. When transitioning from QSILIT and QWLIT
states to QSPECIAL upon scanning @, return a @ token, which
is now parsed in the grammar.
* parser.y (quasi_meta_helper): New static function.
(q_var): Do not handle SYMTOK any more, only the braced
variable syntax. SYMTOK is handled as a n_expr.
Braced vars are handled with explicit '@' token, which
is now produced by the scanner when it shifts from QSILIT
to QSPECIAL.
(quasi_item): No longer necessary to recognize various
forms here such as quotes and splices. Just recognize a n_expr,
preceded by '@'.

* Makefile (GEN_HDRS, LISP_TO_C_STRING): Variables removed.
(%.h: %.tl): Rule removed. The place.h header is no longer
generated from place.tl.
* lisplib.c (place_instantiate): Load place.tl from stdlib directory,
rather than obtaining it from a string literal in generated header
place.h.
* place.tl: Moved to share/txr/stdlib directory.

* hash.c (equal_hash): For conses and vectors, ensure that
distinct permutations lead to different hash codes. This is done by
accumulating the partial hash with a multiplier, rather than just
adding subhashes.
