Most changes are mechanical replacement of 'retw' instruction with
'abi_ret' macro, defined to 'retw' or 'ret' according to ABI.
Assembly code that makes calls is duplicated for call0 ABI with changed
register numbers for parameters/return value and call instruction.
'entry' instructions are replaced with 'abi_entry' macro.
More interesting changes:
- non-leaf assembly functions (e.g. _dl_tlsdesc_dynamic,
_dl_linux_resolve, SYSCALL_ERROR_HANDLER, PSEUDO) now need to preserve
registers around intermediate calls they make, use temporary stack
frame for that;
- setjmp/longjmp only need to save and restore return address, stack
pointer and callee-saved registers in the jmpbuf;
- __clone and syscall functions had hardcoded offsets to parameter
passed on stack, on call0 ABI they don't need stack frame, so the
offset is different. Replace these offsets with FRAMESIZE macro.

posix_fallocate implementation in uClibc relies on fallocate
system call - it just returns what fallocate returns. However
fallocate returns -1 on failure and assigns an error number
to errno variable. In the same time posix_fallocate must
return an error number but not -1.
What does this patch: if fallocate returns -1 then posix_fallocate
returns errno. Otherwise posix_fallocate returns 0 on success.
However there is a side effect - posix_fallocate sets errno on
failure because fallocate does it. But POSIX does not forbid it
thus it's not a problem.

For common generic syscall ABI fallocate syscall handler in kernel
expects a 64-bit signed arguments for offset and len. However uClibc
has 2 wrappers for this syscall: fallocate and fallocate64.
On 32-bit machines fallocate (not fallocate64) expects 32-bit values of
offset and len. Thus in this case uClibc's fallocate must pass to the
syscall those values with sign extension. High word of 64-bit value must
be 0 or 0xFFFFFFFF depending on sign of the original 32-bit value (offset
or len). It is how sign extansion works - all high bits of the negative
value must be 1.
So on 32-bit machines uClibc's fallocate does sign extension incorrectly
when 32-bit values are passed (offset or len). It just fills the second
word of 64-bit value by zeros. E.g. fallocate works incorrectly when offset
or length is negative value - in this case kernel thinks that positive
values are passed.
Solution is to call fallocate64 from fallocate and pass 32-bit values of
offset and len to fallocate64. off_t type is automatically converted to
off64_t with an appropriate sign extension. Then fallocate64 invokes
kernel's system call properly.
This error is detected in LTP's test kernel/syscalls/fallocate02:
----------->8----------
fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0
fallocate(..., 1, 1024, -1024) failed, expected errno:22: TEST_ERRNO=0
fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0
fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0
----------->8----------
fallocate does not emit an error because negative values are passed to the
kernel without sign extension and kernel thinks that it got valid positive
values.

fallocate system call must return 0 on success. On error, -1 is returned
and errno is set to indicate the error.
However there is an error in fallocate which is fixed by this patch - it
does not set errno and returns invalid value on error (it returns error
code instead of -1).
This error is detected in LTP's test kernel/syscalls/fallocate02:
----------->8----------
fallocate(..., 1, 0, 1024) failed, expected errno:9: TEST_ERRNO=0
fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0

fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0
fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0

access to the jmp_buf structure occasionally happens asymmetrically:
fields defined in pointer size width (64 on N32) can be accessed as
32-bit words, but in that case, a̲l̲l̲ involved code must agree on that…

Existing version of memset() relies on existence of 64-bit load/stores.
While ARC HS38 may not have those instructions implemented in SoC.
Proposed implementation checks if "-mno-ll64" option was passed to gcc
(for ARCv2 "-mll64" is set implicitly by default) by checking __LL64__
definition and if it is not defined uses 32-bit load/stores.

ret_ERRVAL is used by mq_timedsend and mq_timedreceive, it needs to be
defined to retw, otherwise error return from those functions segfaults.

Didn't expect signal from child: got `Segmentation fault'
.... tst-mqueue2

Cancellable syscalls use call8 to call functions that enable/disable
cancellation, thus they cannot use the default FRAMESIZE.
Redefine FRAMESIZE for such syscalls.

uClibc doesn't define signal info for the SIGSYS signal which is issued
in case of hitting a syscall prohibited by seccomp.
This is sad as it makes debugging seccomp filter policies impossible on
some architectures (at least ARM and PowerPC, maybe also others) which
do not coincidentally set si_value.sival_int as the syscall number.
To fix this, import the definitions and macros needed from glibc.

The current code implements the 'm' modifier only for 's'
conversions and would cause a segfault if it was used for 'c'
or '[' conversions. This patch extends the code to cover these
cases too.
The original version could write scanned data outside the passed buffer
because index i used in the '[' conversion handling block was clobbered.

when building uClibc with -O0 (DODEBUG build) the default sigrestorer
had some extra glue code generated for stack manipulation which was
messing up resume from signal path.
So annotate the function with -Os so that gcc would only generate the
bare min 2 instruction TRAP sequence
