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).

-Subject: [PATCH] struct siginfo vs. siginfo_t
-
-gdb/
-	* amd64-linux-nat.c (amd64_linux_siginfo_fixup): Use siginfo_t instead
-	of struct siginfo.
-	* arm-linux-nat.c (arm_linux_stopped_data_address): Likewise.
-	* ia64-linux-nat.c (ia64_linux_stopped_data_address): Likewise.
-	* linux-nat.c (linux_nat_siginfo_fixup, siginfo_fixup)
-	(linux_xfer_siginfo, linux_nat_set_siginfo_fixup)
-	(linux_nat_get_siginfo): Likewise.
-	* linux-nat.h (struct lwp_info, linux_nat_set_siginfo_fixup)
-	(linux_nat_get_siginfo): Likewise.
-	* linux-tdep.c (linux_get_siginfo_type): Likewise.
-	* ppc-linux-nat.c (ppc_linux_stopped_data_address): Likewise.
-	* procfs.c (gdb_siginfo_t): Likewise.
-
-gdbserver/
-	* linux-arm-low.c (arm_stopped_by_watchpoint): Use siginfo_t instead of
-	struct siginfo.
-	* linux-low.c (siginfo_fixup, linux_xfer_siginfo): Likewise.
-	* linux-x86-low.c (x86_siginfo_fixup): Likewise.
-	* linux-low.h: Include <signal.h>.
-	(struct siginfo): Remove forward declaration.
-	(struct linux_target_ops) <siginfo_fixup>: Use siginfo_t instead of
-	struct siginfo.
