[review] Share windows_thread_info between gdb and gdbserver
Change URL: https://gnutoolchain-gerrit.osci.io/r/c/binutils-gdb/+/407
......................................................................
Share windows_thread_info between gdb and gdbserver
This introduces a new file, nat/windows-nat.h, which holds the
definition of windows_thread_info. This is now shared between gdb and
gdbserver.
Note that the two implementations different slightly. gdb had a
couple of fields ("name" and "reload_context") that gdbserver did not;
while gdbserver had one field ("base_context") that gdb did not, plus
better comments. The new file preserves all the fields, and the
comments.
