Rather than manually include tconfig.h when we think we'll need it (which
is error prone as it can define symbols we expect from config.h), have it
be included directly by config.h. Since we know we have to include that
header everywhere already, this will make sure tconfig.h isn't missed.
It should also be fine as tconfig.h is supposed to be simple and only set
up a few core defines for the target.
This allows us to stop symlinking it in place all the time and just use
it straight out of the respective source directory.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
Before POSIX standardized strsignal(), old systems would hide the
prototype unless the normal extension defines were enabled. So use
the AC_USE_SYSTEM_EXTENSIONS helper for that.
Then make sure we include string.h ourselves in nrun.c rather than
relying on implicit includes via other sim headers.

This isn't entirely correct in that it assumes the signal numbering of
the target and host match, but seeing as we already make that assumption
in a few places, this patch doesn't make the situation any worse.

(cb_store_target_endian): Renamed from store, new first parameter
host_callback *cb, drop last parameter big_p. Take endianness
from cb.
(cb_host_to_target_stat): Change to use cb_store_target_endian.
Remove variable big_p.
* nrun.c (main): Initialize default_callback.target_endian.
* sim-options.c (STANDARD_OPTIONS): New member OPTION_SYSROOT.
(standard_options): Support --sysroot=<path>.
(standard_option_handler): Handle OPTION_SYSROOT.
* syscall.c (simulator_sysroot): Define, initialized empty.
(get_path): Prepend simulator_sysroot to absolute file path.
[HAVE_STRING_H]: Include string.h.
[!HAVE_STRING_H && HAVE_STRINGS_H]: Include strings.h.
* nrun.c [HAVE_UNISTD_H]: Include unistd.h.
(main): If simulator_sysroot is not empty, chdir there.
* sim-config.h (simulator_sysroot): Declare.
that image properties such as endianness can be checked.
More strongly document the expected behavour of each of the sim_*
interfaces.
Add default endian argument to simulator config macro
SIM_AC_OPTION_ENDIAN. Use in sim_config.
