We previously specified a few known register groups for the 'tui reg'
command. Other register groups could be accessed, but only by using the
'tui reg next' command and cycling through all the groups.
This commit removes the hard coded sub-commands of 'tui reg' and instead
adds dynamic completion of sub-commands based on the architecturally
defined register groups, giving immediate access to all available
register groups.
There is still the 'next' and 'prev' commands for cycling through the
register groups if that's wanted.
The new code maintains the ability to only enter partial names for
register groups, which is something we got for free when using the
standard sub-command mechanism.
The register (and register group) completer has been changed to use
get_current_arch rather than using the architecture of the currently
selected frame. When the target is running, this is equivalent,
however, when the target is not running, using get_current_arch will
provide results from the default architecture.

If we are reading/writing from a memory object, the length represents
the number of "addresses" to read/write, so the addressable unit size
needs to be taken into account when allocating memory on gdb's side.

The Blackfin port had some TRACE_xxx macros for easily logging trace data.
Use these as a base for common ones that have a simple form and match the
existing sets of helper macros.
The cgen code declares some macros/funcs using the trace_xxx prefix, but
the code isn't generic and only works with cgen targets. This is blocking
the creation of new common trace functions.
Let's blindly add cgen_xxx prefixes to all these symbols. Some already
use this convention to avoid conflicts, so it makes sense to align them.
In the future we might want to move some to the common trace core, but
one thing at a time.
Types used for some variables could not be used for 32 bits, causing a
compilation failure.
This patch adds a cast to force a quite compilation, but at the same
time it bails out in the case that the cast performed is not safe, i.e.
in the case where the debuggee is 64bit and debugger is 32bit.
Documentation was also affected, once a different version of texinfo the
docs could not be build.

In aarch64.cc, Erratum_stub::STUB_ADDR_ALIGN and Reloc_stub::STUB_ADDR_ALIGN

the references go unresolved.

When laying out .debug_* sections, we translate the names of compressed

This patch adds -O0 to gold script_test_12 test, hoping that compiler
won't change the order of globel variables that the test assumes.

testsuite/Makefile.in: Regenerate.
First we convert the ETRACE_P to STRACE_EVENTS_P. This means we move from
using the sim_events.trace storage to the common sim_state_base.trace_data
array. With that deleted, the common trace init code can be simplified so
the sim state works the same as the sim cpu.
This is the only sim that sets up its own WITH_TRACE mask and it conflicts
with the user setting their own list at configure time. Drop it to match
all the other sims.

The syscall path was the only code checking the custom exception state
after recent cleanups. Once we change that to the common engine halt
function, we can delete that state entirely.
This also helps highlight some other dead code that we can cull.

While reimplementing <library-list/> I found from expat-2.0.1-11.fc15.x86_64:
warning: while parsing target library list (at line 1): Required attribute "version" of <library-list-svr4> not specified
I believe the same bug has to apply for existing FSF gdbserver but I do not
have any <library-list/> platform to test it (I did not try to build MinGW).
features/library-list.dtd:
<!ATTLIST library-list version CDATA #FIXED "1.0">
http://www.xml.com/pub/a/98/10/guide0.html?page=3 says:
In this case, the attribute is not required, but if it occurs, it must
have the specified value.
Which would suggest gdbserver is right but solib-target.c is wrong. One could
also make gdbserver explicit for the version (if those 14 bytes are not of
a concern).
