This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Add new set/show commands to set the processor that is used for enabling
errata workarounds when decoding branch trace.
The general format is "<vendor>:<identifier>" but we also allow two
special values "auto" and "none".
The default is "auto", which is the current behaviour of having GDB
determine the processor on which the trace was recorded.
If that cpu is not known to the trace decoder, e.g. when using an old
decoder on a new system, decode may fail with "unknown cpu". In most
cases it should suffice to 'downgrade' decode to assume an older cpu.
Unfortunately, we can't do this automatically.
The other special value, "none", disables errata workarounds.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This patch allows gdbserver to continue recording after disconnect. On
reconnect, the recorded data is accessible to gdb as if no disconnect happened.
A possible application for this feature is remotely examine bugs that occur
at irregular intervals, where maintaining a gdb connection is inconvenient.
This also fixes the issue mentioned here:
