gdb: convert to the package infrastructure
This commit converts gdb to the package infrastructure, and therefore
moves it from toolchain/gdb to package/gdb.
The target package is now visible in "Package selection for the
target" => "Debugging, profiling and benchmark". The main option,
"gdb", forcefully selects the "gdbserver" sub-option by
default. Another sub-option, "full debugger" allows to install the
complete gdb on the target. When this option is enabled, then
"gdbserver" is no longer forcefully selected. This ensures that at
least gdbserver or the full debugger gets built/installed, so that the
package is not a no-op.
The host debugger is still enabled through a configuration option in
"Toolchain". It is now visible regardless of the toolchain type (it
used to be hidden for External Toolchains). The configuration options
relative to the host debugger are now in package/gdb/Config.in.host,
similar to how we have package/binutils/Config.in.host.
Since gdb is now a proper package, it is no longer allowed to 'select
BR2_PTHREADS_DEBUG' to ensure thread debugging is available when
needed. Instead, it now 'depends on
BR2_TOOLCHAIN_HAS_THREADS_DEBUG'. This option, in turn, is selected by
the different toolchain backends when appropriate. The
'BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED' option is removed, since
we no longer need to know when it is allowed to 'select
BR2_PTHREADS_DEBUG'. Also, the 'BR2_PTHREADS_DEBUG' option is moved to
appear right below the thread implementation selection (in the case of
the Buildroot toolchain backend).

gdb: drop support for Microblaze
Microblaze support was never upstreamed in gdb. We currently use a gdb
from the Xilinx Github repository, but this gdb is based on 7.6, and
has never been updated in the last 4 years. There are no other active
branches at https://github.com/Xilinx/gdb/branches.
Xilinx has a slightly newer gdb, based on 7.7, available at
https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb. However,
it's apparently only available in the form of stack of big patches
(https://github.com/Xilinx/meta-xilinx/tree/master/recipes-microblaze/gdb/files).
Currently, gdb on Microblaze fails to build in various conditions:
* Against glibc, with "error: conflicting types for 'ps_lgetfpregs'"
* Against musl, with "error: unknown type name 'elf_gregset_t'"
While those issues can probably be fixed, the fact that there is no
active upstream significantly reduces the incentive to fix those
problems.
Therefore, let's drop support for gdb on Microblaze entirely.

package/gdb: add version 8.1
https://sourceware.org/ml/gdb-announce/2018/msg00001.html
gdb 8.1 has a new optional dependency on mpfr, which according to the
NEWS file:
GDB now uses the GNU MPFR library, if available, to emulate target
floating-point arithmetic during expression evaluation when the
target uses different floating-point formats than the host. At
least version 3.1 of GNU MPFR is required.
So for the target gdb, this is unnecessary, and therefore we
forcefully disable mpfr support by passing --without-mpfr.
For the host gdb, it would potentially be useful, but since it's a new
feature that isn't essential, we for now keep it disabled as well. An
option may be added later if needed.
To avoid gnulib issues with uClibc/musl, we need to pass additional
configure/make variables, like is done in OpenEmbedded [1].
[1] http://git.openembedded.org/openembedded-core/tree/meta/recipes-devtools/gdb/gdb_8.1.bb?id=02664a8dcd1ebb6cd77248e1b97a78390ea06033#n9
We re-add the same patches as the ones present for gdb 8.0.1, except
0004-nat-linux-ptrace.c-add-missing-gdb_byte-cast.patch, which was
merged upstream.
