[gdb, hurd] Work around conflict between Mach's 'thread_info' function, and GDB's 'thread_info' class
In file included from ./nm.h:25:0,
from [...]/gdb/defs.h:423,
from [...]/gdb/gdb.c:19:
[...]/gdb/regcache.h:35:46: warning: 'get_thread_regcache' initialized and declared 'extern'
extern struct regcache *get_thread_regcache (thread_info *thread);
^~~~~~~~~~~
[...]/gdb/regcache.h:35:46: error: 'regcache* get_thread_regcache' redeclared as different kind of symbol
[...]
[...]/gdb/gdbarch.h:1203:69: error: 'thread_info' is not a type
extern LONGEST gdbarch_get_syscall_number (struct gdbarch *gdbarch, thread_info *thread);
^~~~~~~~~~~
Fixed with a different (self-contained, more maintainable?) approach compared
to what has been done in commit 7aabaf9d4ad52a1df1f551908fbd8cafc5e7597a
"Create private_thread_info hierarchy", and commit
75cbc781e371279f4403045be93b07fd8fe7fde5 "gdb: For macOS, s/thread_info/struct
thread_info/". We don't want to change all the GDB code to everywhere use
'class thread_info' or 'struct thread_info' instead of plain 'thread_info'.
gdb/
* config/i386/nm-i386gnu.h: Don't "#include" any files.
* gnu-nat.h (mach_thread_info): New function.
* gnu-nat.c (thread_takeover_sc_cmd): Use it.
