Joel Brobecker 42a4f53d2b Update copyright year range in all GDB files.
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.

Tom Tromey 7bc02706c3 Avoid -Wnarrowing warnings in struct tramp_frame instances
This avoids -Wnarrowing warnings in struct tramp_frame instances,
replacing uses of -1 with a new ULONGEST_MAX.  It also redefined
TRAMP_SENTINEL_INSN to avoid the same warning.

Alan Hayward a616bb9450 Split size in regset section iterators
In the existing code, when using the regset section iteration functions, the
size parameter is used in different ways.

With collect, size is used to create the buffer in which to write the regset.
(see linux-tdep.c::linux_collect_regset_section_cb).

With supply, size is used to confirm the existing regset is the correct size.
If REGSET_VARIABLE_SIZE is set then the regset can be bigger than size.
Effectively, size is the minimum possible size of the regset.
(see corelow.c::get_core_register_section).

There are currently no targets with both REGSET_VARIABLE_SIZE and a collect
function.
In SVE, a corefile can contain one of two formats after the header, both of
which are different sizes. However, when writing a core file, we always want
to write out the full bigger size.

To allow support of collects for REGSET_VARIABLE_SIZE we need two sizes.
This is done by adding supply_size and collect_size.
