I am not sure if this is going to bring any compatibility issues.
If yes, we need to remove this patch and add "useable" to the list of
ignored words instead.

@gpregs_case is a bit vague name, lets
define traditional @mode here.

Dump TLS with the help of SYS_get_thread_area.
Primary for 32-bit applications, but this also may be used by
mixed 64/32 bit code. I do not enable dumping for 64 bit unless
we'll meet such code, but include 3 user_desc entries of TLS
as not present in 64-bit images.
That's arguable and I may include user_descs only for compat tasks.

Introduced user_regs_struct32.
Other changes mainly are reforming existing code to use the new
register sets union.
For protobuf images - reuse user_x86_regs_entry for both compatible
and native tasks with enum in the beggining that describes register
set type. That's better and simpler, than introducing a new 32-bit
register set for compatible tasks. I tried to do this firstly with
oneof keyword:
499c93ae0e
But protobuf supports oneof keyword only from recent version 2.6.0,
so I tried to rework it into enum + 2 register sets:
aab4489bd4
But that did not work either because restorer pie takes gpregs as
thread_restore_args parameter and UserRegsEntry shouldn't contain
pointers, but structure objects. This may be fixed by redefining
UserRegsEntry not as typedef for UserX86RegsEntry, but containing
needed objects, than treat it right for restorer - but that's
more complicated that reusing user_x86_regs_entry.

But keep @protobuf as a symlink: we have
this path encoded in sources. Gonna be
removed with time.
