error test (previously only errno was checked, but the return
value of strtod() should be checked as well). [Bug: 4118].
* tests/exec.test: Added test for proper conversion of UTF data
when used with "<< $dataWithUTF" on exec's.
* unix/tclUnixPipe.c (TclpCreateTempFile): Added
Tcl_UtfToExternalDString call, so that if there is UTF content in
the string it will be properly converted to the system encoding
before being written [Bug: 4030].
(TclpCreateTempFile): Added a check on the return value of tmpnam;
some systems (Linux, for example) will start to return NULL after
tmpnam has been called TMP_MAX times; not checking for this can
have bad results (overwriting temp files, core dumps, etc.)

* tests/parseExpr.test:
* tests/string.test:
* generic/tclGet.c:
* generic/tclInt.h:
* generic/tclObj.c:
* generic/tclParseExpr.c:
* generic/tclUtil.c:
* generic/tclExecute.c: added TclCheckBadOctal routine to enhance
error message checking for when users use invalid octal numbers
(like 08), as well as replumbed the Expr*Funcs with a new
VerifyExprObjType to simplify type handling.
* tests/expr.test:
* generic/tclCompile.c: fixed 'bad code length' error for
'expr + {[incr]}' case, with new test case [Bug: 3736]
and seg fault on 'expr + {[error]}' (different cause) that
was caused by a correct optimization that didn't correctly
track how it was modifying the source string in the opt.
The optimization was removed, which means that:
expr 1 + {[string length abc]}
will be not be compiled inline as before, but this should be
written:
expr {1 + [string length abc]}
which will be compiled inline for speed. This prevents
expr 1 + {[mindless error]}
from seg faulting, and only affects optimizations for
degenerate cases [Bug: 3737]

* doc/OpenFileChnl.3:
* doc/file.n:
* tests/cmdAH.test:
* tclIO.c:
* tclCmdAH.c: added "file channels ?pattern?" tcl command, with
associated Tcl_GetChannelNames and Tcl_GetChannelNamesEx public
C APIs (added to tcl.decls as well), with docs and tests.
* generic/tclCompile.c: add TCL_TOKEN_VARIABLE to the part types
that cause differed compilation for exprs, to correct the expr
double-evaluation problem for vars. Added test cases.
