locale_impl.h could have been used, but this function is completely
independent of anything else, and preserving that property seems nice.

isspace can be a bottleneck in a simple parser, inlining it
gives slightly smaller and faster code
src/locale/pleval.o already had this optimization, the size
change for other libc functions for i386 is
src/internal/intscan.o 2134 2118 -16
src/locale/dcngettext.o 1562 1552 -10
src/network/res_msend.o 1961 1940 -21
src/network/lookup_name.o 2627 2608 -19
src/network/getnameinfo.o 1814 1811 -3
src/network/lookup_serv.o 643 624 -19
src/stdio/vfscanf.o 2675 2663 -12
src/stdlib/atoll.o 117 107 -10
src/stdlib/atoi.o 95 91 -4
src/stdlib/atol.o 95 91 -4
src/time/strptime.o 1515 1503 -12
(TOTALS) 432451 432321 -130

using an operator precedence parser the code size
became smaller and it is only slower by about %10
size of old vs new pleval.o on different archs:
(with inlined isspace added to pleval.c for now)
old:
text data bss dec hex filename
828 0 0 828 33c pl.i386.o
1152 0 0 1152 480 pl.arm.o
1704 0 0 1704 6a8 pl.mips.o
1328 0 0 1328 530 pl.ppc.o
992 0 0 992 3e0 pl.x64.o
new:
text data bss dec hex filename

const parsing, depth accounting and failure handling was changed
a bit so the generated code is slightly smaller.

the new code in dcngettext was written by me, and the expression
evaluator by Szabolcs Nagy (nsz).
