Read $GDBHISTSIZE instead of $HISTSIZE
The HISTSIZE environment variable is generally expected to be read by
shells, not by applications. Some distros for example globally export
HISTSIZE in /etc/profile -- with the intention that it only affects
shells -- and by doing so it renders useless GDB's own mechanism for
setting the history size via .gdbinit. Also, annoyances may arise when
HISTSIZE is not interpreted the same way by the shell and by GDB, e.g.
PR gdb/16999. That can always be fixed on a shell-by-shell basis but it
may be impossible to be consistent with the behavior of all shells at

Call target_terminal_ours_for_output() before refreshing TUI's frame info
In some cases tui_show_frame_info() may get called while the inferior's

we absolutely need to have our terminal settings in effect because the
function is responsible for redrawing TUI's windows following a change
in the selected frame or a change in the PC. If our terminal settings
are not in effect, the screen does not get redrawn properly, causing
temporary display artifacts (which can be fixed via ^L).
This scenario happens most prominently when stepping through a program

Allow gdb to find debug symbols file by build-id for PE file format also
This promotes BFD's struct elf_build_id to the generic struct bfd_build_id,
populated when an ELF or PE BFD is read.
gdb is updated to use that, and to use the build-id to find symbols for PE files
also.
There is currently no generic way to extract the build-id from an object file,
perhaps an option to objdump to do this might make sense?

gdb: Rework command completion on 'tui reg'.
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.

Fix gdbserver <library-list> and its #FIXED version="1.0"
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).
