* generic/tclGet.c (Tcl_GetDouble): Added additional conditions to

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.)
