	common/lib/libc/arch/i386/string/small/strchr.S: revision 1.3
Look for the character to locate before checking for the NUL character
As documented in PR port-i386/49208, this fixes strchr(s, '\0'), as used by
the FAT first-stage bootloader on x86 (bootxx_msdos).
strchr(s, '\0') is otherwise equivalent to strlen(string), which would
probably look nicer in the original file, dosfs.c from libsa.
Confirmed working in qemu and on real hardware.

	sys/dev/iscsi/iscsi_send.c: revision 1.10
The "throttling" code in the in-kernel iSCSI initiator is very questionable;
it sleeps on a ccb that appears highly unlikely to wake up, since it seems
to be waiting to _submit_ that very ccb!  This is doubtless why someone tried
to disable it in the default case via several #defines.
Unfortunately one of those #defines is later tested backwards.  Fix that.
The in-kernel initiator now seems to survive a system build without hanging.
