[GDBserver] Multi-process + multi-arch
This patch makes GDBserver support multi-process + biarch. Currently, if you're debugging more than one process at once with a single gdbserver (in extended-remote mode), then all processes must have the same architecture (e.g., 64-bit vs 32-bit). Otherwise, you see this: Added inferior 2 [Switching to inferior 2 [<null>] (<noexec>)] Reading symbols from /home/pedro/gdb/tests/main32...done. Temporary breakpoint 2 at 0x4004cf: main.

Even though the process was running a 32-bit program, GDBserver sent back to GDB a register set in 64-bit layout. A patch (http://sourceware.org/ml/gdb-patches/2012-11/msg00228.html) a while ago made GDB track a target_gdbarch per inferior, and as consequence, fetch a target description per-inferior. This patch is the GDBserver counterpart, that makes GDBserver keep track of each process'es XML target description and register layout. So in the example above, GDBserver will send the correct register set in 32-bit layout to GDB. A new "struct target_desc" object (tdesc for short) is added, that holds the target description and register layout information about each process. Each `struct process_info' holds a pointer to a target description. The regcache also gains a pointer to a target description, mainly for convenience, and parallel with GDB (and possible future support for programs that flip processor modes). The low target's arch_setup routines are responsible for setting the process'es correct tdesc. This isn't that much different to how things were done before, except that instead of detecting the inferior process'es architecture and calling the corresponding init_registers_FOO routine, which would change the regcache layout globals and recreate the threads' regcaches, the regcache.c globals are gone, and the init_registers_$BAR routines now each initialize a separate global struct target_desc object (one for each arch variant GDBserver supports), and so all the init_registers_$BAR routines that are built into GDBserver are called early at GDBserver startup time (similarly to how GDB handles its built-in target descriptions), and then the arch_setup routine is responsible for making process_info->tdesc point to one of these target description globals. The regcache module is all parameterized to get the regcache's layout from the tdesc object instead of the old register_bytes, etc. globals. The threads' regcaches are now created lazily. The old scheme where we created each of them when we added a new thread doesn't work anymore, because we add the main thread/lwp before we see it stop for the first time, and it is only when we see the thread stop for the first time that we have a chance of determining the inferior's architecture (through the_low_target.arch_setup). Therefore when we add the main thread we don't know which architecture/tdesc its regcache should have. This patch makes the gdb.multi/multi-arch.exp test now pass against (extended-remote) GDBserver. It currently fails, without this patch. The IPA also uses the regcache, so it gains a new global struct target_desc pointer, which points at the description of the process it is loaded in. Re. the linux-low.c & friends changes. Since the register map etc. may differ between processes (64-bit vs 32-bit) etc., the linux_target_ops num_regs, regmap and regset_bitmap data fields are no longer sufficient. A new method is added in their place that returns a pointer to a new struct that includes all info linux-low.c needs to access registers of the current inferior. The patch/discussion that originally introduced linux-low.c:disabled_regsets mentions that the disabled_regsets set may be different per mode (in a biarch setup), and indeed that is cleared whenever we start a new (first) inferior, so that global is moved as well behind the new `struct regs_info'. On the x86 side: I simply replaced the i387-fp.c:num_xmm_registers global with a check for 64-bit or 32-bit process, which is equivalent to how the global was set. This avoided coming up with some more general mechanism that would work for all targets that use this module (GNU/Linux, Windows, etc.).
