christos | Import gdb-17.1, previous was 16.3
This version of GDB includes the following changes and enhancements:
* x86-64 CET shadow stack support
* Debugging Linux programs that use AArch64 Guarded Control Stacks
* GDB record feature now supports rv64gc architectures
* 'info threads' command support for two new options '-stopped' and
'-running' to limit the list of displayed threads.
* On Linux and FreeBSD, the addresses shown by the 'info
sharedlibrary' command are now for the full memory range
allocated to the shared library.
* Linux checkpoints now work with multiple inferiors
* Improved linker namespace support
* Warnings and error messages now start with an emoji (warning
sign, or cross mark) if supported by the host charset.
Configurable.
* Built-in support for TLS on Linux as backup when libthread_db is
not available. Supported on the x86_64, aarch64, ppc64, s390x,
and riscv architectures, when compiled with GLIBC or MUSL.
* New command "set riscv numeric-register-names" to display
risc-v registers using their numeric names instead of their
ABI names.
* The Alpha target now supports target descriptions.
Python API enhancements:
* New class gdb.Color for dealing with colors, and new constant
gdb.PARAM_COLOR
* New gdb.ParameterPrefix class, to create new 'set/show' command
prefixes.
* New attribute gdb.Value.is_unavailable, this checks for
unavailability like gdb.Value.is_optimized_out checks for
optimized out values.
* New gdb.warning() function to print a warning message, with
GDB's standard 'warning' prefix (see emoji support entry below)
* gdb.execute has an additional 'styling' argument.
* Prefix commands (gdb.Command sub-classes) that don't have an
invoke method now behave like builtin prefix commands when
invoked without a sub-command name.
* Setting the documentation string (__doc__) of a gdb.Parameter
sub-class to the empty string, means GDB will only display the
set_doc or show_doc strings in the set/show help output.
Guile API enhancements:
* New type for dealing with colors and constant PARAM_COLOR
* Prefix commands (using make-command) that don't have a #:invoke
property will now behave like builtin prefix commands when
invoked without a sub-command name.
* Eliding the #:doc string from make-parameter now means that
GDB will use a default documentation string.
* Setting #:doc to the empty string for make-parameter means GDB
will only display the #:set_doc or #:show_doc strings in the
set/show help output.
Debugger Adapter Protocol changes:
* GDB now supports the "completions" request.
* New "--binary-output" command line option to disable LF
translations (Windows only)
New convenience variables:
* $_colorsupport providing a comma-separated list of color space
names supported by the terminal.
* $linker_namespace_count and $_linker_namespace provide the list
of active linker namespaces.
Remote package additions and changes:
* New 'binary-upload+' value in qSupported reply
* The 'vFile:stat' command implementation has been corrected to
use stat rather than lstat.
* New vFile:lstat packet, useful for handling symbolic links
* Support for the "id_str" attribute in 'qXfer:threads:read' XML
answer.

* The =library-unloaded event now includes the 'ranges' field and
the 'still-in-use' field.

format is deprecated, and will be removed in GDB 18.
