When using hardware step for doing stepping, the existing DSCR records
the event as external debug request. This will generate a SIGINT event
to GDB and causes it to stop the stepping process.
For aarch64, read DESR to check if the event is a hardware step and set
state to DBG_REASON_SINGLESTEP.
With this patch, GDB can now do source level stepping.

Define a target_addr_t type to support 32-bit and 64-bit addresses at
the same time. Also define matching TARGET_PRI*ADDR format macros as
well as a convenient TARGET_ADDR_FMT.
In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000)
be least invasive by leaving the formatting unchanged apart from the
type;
for generic code adopt TARGET_ADDR_FMT as unified address format.
Don't silently change gdb formatting here, leave that to later.
Add COMMAND_PARSE_ADDRESS() macro to abstract the address type.
Implement it using its own parse_target_addr() function, in the hopes
of catching pointer type mismatches better.
Add '--disable-target64' configure option to revert to previous 32-bit
target address behavior.

This bug was already attempted to fix in an earlier patch but
merging the "defer-examine" feature caused a regression, which this patch

When SRST is never enabled, the global jtag_srst variable is left at its
initial state, that is, -1, and it does _not_ mean SRST is currently
asserted. Same about TRST.
Fixes "reset halt" in cases when srst_pulls_trst but srst usage is not
enabled.

Parts of doc/help kept reading 'sector' instead of 'protection block'.
flash_driver_protect() parameter range testing did not switched
to bank->num_prot_blocks.
This change fixes it.

These libraries override the used CFLAGS without adding the
defaults. This didn't have any effect until change
http://openocd.zylin.com/3870 (ef4c139). Restore by adding
AM_CLAGS to the per-target CFLAGS.
Interestingly, automake seems to clear the CFLAGS for the target
even if the override variable is only mentioned within a non-active
conditional branch, such as the IS_MINGW for the affected libraries.

Add a helper to hide the platform-dependent method to get a
canonical, absolute, /-separated path to the executable.
Use this and the relative path from BINDIR to PKGDATADIR to
construct a search path that finds the scripts even if the
installation dir is moved, as long as the structure below $prefix
is maintained.
This method should fully support all the tricks you can to with
autotools to customize the installed layout such as overriding the
default directories at configure-time and overriding the configured
directories at build-time.
The exe path detection methods are combined from
