Andrew Burgess bf616be991 gdb/gdbserver: share some code relating to target description creation 
This commit is part of a series to share more of the x86 target
description creation code between GDB and gdbserver.

Unlike previous commits which were mostly refactoring, this commit is
the first that makes a real change, though that change should mostly
be for gdbserver; I've largely adopted the "GDB" way of doing things
for gdbserver, and this fixes a real gdbserver bug.

On a x86-64 Linux target, running the test:

  gdb.server/connect-with-no-symbol-file.exp

results in two core files being created.  Both of these core files are
from the inferior process, created after gdbserver has detached.

In this test a gdbserver process is started and then, after gdbserver
has started, but before GDB attaches, we either delete the inferior
executable, or change its permissions so it can't be read.  Only after
doing this do we attempt to connect with GDB.

As GDB connects to gdbserver, gdbserver attempts to figure out the
target description so that it can send the description to GDB, this
involves a call to x86_linux_read_description.

In x86_linux_read_description one of the first things we do is try to
figure out if the process is 32-bit or 64-bit.  To do this we look up
the executable via the thread-id, and then attempt to read the
architecture size from the executable.  This isn't going to work if
the executable has been deleted, or is no longer readable.

And so, as we can't read the executable, we default to an i386 target
and use an i386 target description.

A consequence of using an i386 target description is that addresses
are assumed to be 32-bits.  Here's an example session that shows the
problems this causes.  This is run on an x86-64 machine, and the test
binary (xx.x) is a standard 64-bit x86-64 binary:

  shell_1$ gdbserver --once localhost :54321 /tmp/xx.x

  shell_2$ gdb -q
  (gdb) set sysroot
  (gdb) shell chmod 000 /tmp/xx.x

  (gdb)

Notice the difference between the mappings reported via GDB and those
reported directly from the kernel via /proc/PID/maps, the addresses of
every mapping is clamped to 32-bits for GDB, while the kernel reports
real 64-bit addresses.

Notice also that the $pc value is a 32-bit value.  It appears to be
within one of the mappings reported by GDB, but is outside any of the
mappings reported from the kernel.

And this is where the problem arises.  When gdbserver detaches from
the inferior we pass the inferior the address from which it should
resume.  Due to the 32/64 bit confusion we tell the inferior to resume
from the 32-bit $pc value, which is not within any valid mapping, and
so, as soon as the inferior resumes, it segfaults.

If we look at how GDB (not gdbserver) figures out its target
description then we see an interesting difference.  GDB doesn't try to
read the executable.  Instead GDB uses ptrace to query the thread's
state, and uses this to figure out the if the thread is 32 or 64 bit.

If we update gdbserver to do it the "GDB" way then the above problem
is resolved, gdbserver now sees the process as 64-bit, and when we
detach from the inferior we give it the correct 64-bit address, and
the inferior no longer segfaults.

Now, I could just update the gdbserver code, but better, I think, to
share one copy of the code between GDB and gdbserver in gdb/nat/.
That is what this commit does.

The cores of x86_linux_read_description from gdbserver and
x86_linux_nat_target::read_description from GDB are moved into a new
file gdb/nat/x86-linux-tdesc.c and combined into a single function
x86_linux_tdesc_for_tid which is called from each location.

This new function does things mostly the GDB way, some changes are
needed to allow for the sharing; we now take some pointers for where
the shared code can cache the xcr0 and xsave layout values.

Another thing to note about this commit is how the functions
i386_linux_read_description and amd64_linux_read_description are
handled.  For now I've left these function as implemented separately
in GDB and gdbserver.  I've moved the declarations of these functions
into gdb/arch/{i386,amd64}-linux-tdesc.h, but the implementations are
left where they are.

A later commit in this series will make these functions shared too,
but doing this is not trivial, so I've left that for a separate
commit.  Merging the declarations as I've done here ensures that
everyone implements the function to the same API, and once these
functions are shared (in a later commit) we'll want a shared
declaration anyway.
