Warning, behaviour change: before this patch if a timer callback
returned an error, the other handlers in the list were not called.
This patch fixes two different issues with the way timer callbacks are
called:
1. The function is not designed to be reentrant but a nested call is
possible via: target_handle timer event -> poll -> target events
before/after reexaminantion -> script_command_run ->
target_call_timer_callbacks_now . This patch makes function a no-op
when called recursively;
2. The current code can deal with the case when calling a handler
leads to its removal but not when it leads to removal of the next
callback in the list. This patch defers actual removal to consolidate
it with the calling loop.
These bugs were exposed by Valgrind.

Cortex A: fix extra memory read and non-word sizes
Without this patch, to perform a memory read, OpenOCD first issues an
LDC instruction into DBGITR in Stall mode (thus executing the
instruction), then switches to Fast mode and reads from DBGDTRTX once
for each word to transfer.
At the very end of the transfer, the final Fast mode read of DBGDTRTX
has, as always, the side effect of re-issuing the LDC instruction. This
causes two problems:
(1) If the word immediately beyond the end of the requested region is
inaccessible, this spurious LDC will cause a fault. On a fast CPU, the
LDC will finish executing by the time the poll of DSCR takes place,
failing the entire memory read. On a slow CPU, the LDC might finish
executing later, leaving an unexpected and confusing sticky fault lying
around for the next operation to see.
(2) If the LDC succeeds, it will leave the loaded word in DBGDTRTX, thus
setting DBGDSCR.TXFULL=1. The cortex_a_read_apb_ab_memory routine
completes without consuming that last word, thus confusing the next
routine that tries to use DBGDTRTX (this may not have any visible effect
on some implementations, because writing to DBGDTRTXint when TXFULL=1 is
defined as Unpredictable, but I believe it caused a visible problem for
me).
With this patch, the bulk mem_ap_sel_read_buf_noincr is modified to omit
the last word of the block. The second-to-last read of DBGDTRTX by that
function will cause the issue of the LDC for the last word. After
switching back to Normal mode and waiting for that instruction to
finish, do a final read of DBGDTRTX to extract the last word into the
buffer, leaving TXFULL=0.
Without this patch, memory accesses are always expanded such that they
are aligned to the access size. With this patch, accesses are issued
exactly as ordered by the caller. The caller is expected to handle
fragments at the beginning and end of the transfer if the address is
unaligned and an unaligned access is not desired.
Without this patch, the DFAR and DFSR registers, which report the
location and status of data faults, are ignored while performing memory
accesses, which could cause problems debugging an OS page fault handler.
With this patch, DFAR and DFSR are preserved across memory accesses, and
DFSR is decoded in the event of a synchronous fault to provide the
caller with more information about the reason for failure.
Thanks to Boris Brezillon for the original patch whose ideas led to the
non-word access mechanism implemented here and to various code reviewers
for their comments.

silently does implicit pointer conversion to (void *) and the
assumption ends up broken without any indication.

stm32f2x: Fix byte order bug.
Do not use buf_set_u32 on integers; they're not buffers.
If using buf_set_u32 on integers, bytes will be exchanged on Big Endian targets.
In this particular case, FLASH_OPTCR was incorrectly written, causing it to often
contain one of these values: 0x00aaaae1, 0x00aaffef, 0x00ffabe1 or 0x00abffe1.
This write-protected the device before flash-programming, causing this command...
flash write_image erase unlock myfile.elf
... to fail, complaining about write-protection.
Repeating the above command would change the OPTCR register each time.
After applying this patch, the OPTCR remains "unchanged".
