toolchain: Improve C library option selection
Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR,
BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options.
Then, for Buildroot toolchains, external toolchains and Crosstool-NG
toolchains, provide visible options that selects the hidden options.
This allows :
* To show a different label and help text in the case of Buildroot
toolchain (do you want to enable feature X ?) and in the case of
external toolchain (is feature X available in your toolchain ?)
* To not show any option when a glibc external toolchain is selected
(since glibc is assumed to support all of largefile, IPv6, RPC,
WCHAR, locale and program invocation) and have them all selected in
that case.
There is some amount of duplication between Buildroot toolchain config
options and Crosstool-NG toolchain config options, because kconfig
doesn't allow to source the same Config.in file twice (even if under
mutually exclusive conditions). This duplication is more readable that
the hack that consists in splitting files in multiple pieces.
However, this commit changes the name of the options visible in the
configuration interface, so existing .config files will have to be
updated accordingly.

toolchain/toolchain-external: add BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER option
Some external toolchains do not have gdbserver available, but the
option BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY is always visible. And
when enabled, this option aborts with an error when gdbserver cannot
be found:
Could not find gdbserver in external toolchain
Due to that, some random configurations fail to build when
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY=y, for example with the Bootlin
toolchains for Microblaze or OpenRISC (because there's no GDB support
for those architectures).
One solution could be to make "Could not find gdbserver in external
toolchain" a warning instead of a hard error, but then nobody would
notice about this issue, in cases where it should legitimately abort
with a hard error.
So, the clean solution would be to add a
BR2_TOOLCHAIN_EXTERNAL_HAS_GDBSERVER. But that means all existing
external toolchains would have to be modified to select this option.
Instead, and as an exception, we chose to use inverted logic, and
create an option that is the opposite:
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER. By default, we assume
external toolchains have gdbserver. If
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER is enabled, we disallow the
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY option.
Note that the case of custom external toolchain does not matter: by
definition they are not tested by the autobuilders, and by definition,
we cannot know in menuconfig if the custom toolchain has or does not
have gdbserver. We could make a user-visible option for it, but that
adds no value over simply erroring out because the gdbserver binary
can't be found.
Similarly, we could add
default y if BR2_PACKAGE_GDB_ARCH_SUPPORTS
but that would make it impossible for someone to include a custom
gdbserver in their external toolchain, and gives no benefit at all.
This will help fixing:

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).

Similarly, we could add
default y if BR2_PACKAGE_GDB_ARCH_SUPPORTS
but that would make it impossible for someone to include a custom
gdbserver in their external toolchain, and gives no benefit at all.
This will help fixing:

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).
