Fix select and _newselect syscall entries

Browse Source 
Change syscall names to match kernel __NR_* constants.
This reverts commit ddcf54969d253582ab2cfdcab8ede9cdae3fb171.

* linux/arm/syscallent.h [82]: Rename "oldselect" to "select".
[142]: Rename "select" to "_newselect".
* linux/bfin/syscallent.h: Likewise.
* linux/i386/syscallent.h: Likewise.
* linux/m68k/syscallent.h: Likewise.
* linux/microblaze/syscallent.h: Likewise.
* linux/powerpc/syscallent.h [82]: Likewise.
* linux/powerpc64/syscallent.h: Likewise.
* linux/sh/syscallent.h: Likewise.
* linux/sh64/syscallent.h: Likewise.
* linux/hppa/syscallent.h [142]: Rename "select" to "_newselect".
* linux/mips/syscallent-n32.h [6022]: Rename "select" to "_newselect".
* linux/mips/syscallent-n64.h [5022]: Likewise.
* linux/mips/syscallent-o32.h [4142]: Likewise.
* linux/s390/syscallent.h [142]: Rename "select" to "_newselect".
* linux/sparc/syscallent.h [230]: Rename "select" to "_newselect".
* tests/oldselect.test: Rename oldselect to select.  Convert
from match_grep to match_diff.
* tests/oldselect.expected: Likewise.
* xselect.c: New file, based on select.c.
* tests/_newselect.c: New file.
* tests/select.c: Replace with a wrapper around xselect.c.
* tests/select.test: Parametrize.
* tests/_newselect.test: New test.
* tests/Makefile.am (check_PROGRAMS): Add _newselect.
(TESTS): Add _newselect.test.
(EXTRA_DIST): Add xselect.c.
* tests/.gitignore: Add _newselect.
