Varobj support for Ada.
This patch adds varobj support for Ada variables. Most of the code
is implemented in a separate Ada-specific file called ada-varobj.c.
The only bits in varobj.c are the functions used as the hooks in
the language-specific varobj's vector.
gdb/ChangeLog:
* ada-varobj.h, ada-varobj.c: New files.
* Makefile.in (SFILES): Add ada-varobj.c.
(HFILES_NO_SRCDIR): Add ada-varobj.h.
(COMMON_OBS): Add ada-varobj.o.

framework for varobj type mutation
This patch introduces the framework necessary to support type mutations.
The only language that currently provides a language-specific hook for
that feature is Ada, but the hook remain unimplemented for now. The
actual implementation is tied to the rest of the varobj code for Ada,
and thus will be provided then.
gdb/ChangeLog:
* varobj.c (ada_value_has_mutated): Add declaration. New function.
(struct language_specific): New field "value_has_mutated".
(languages): Set field "value_has_mutated" in each entry of array.
(varobj_value_has_mutated): New function.
(varobj_udpdate): Add handling of type mutation.
(value_of_root): Add handling of type mutation.

[ia64-linux] Allow libunwind to fetch register 0
On ia64-linux, GDB sometimes prints the following error when trying
to switch to a different task:
(gdb) task 3
Register 0 is not available
This is a random failure that sometimes happens, sometimes does not.
The error comes from the fact that the libunwind library is requesting
the value of register 0 (zero): This eventually leads us to
ia64-linux-nat.c:ia64_linux_fetch_register.
This function relies on ia64_cannot_fetch_register to determine
whether or not we have access to the register's value. The ptrace
interface does not provide the r0 value, and so we end up telling
the regcache that this register's value is not available. And yet,
for r0, we do not need to ask ptrace for its value, since it is
always zero.
So, the fix was to add a special rule for supplying a nul value
when regnum == IA64_GR0_REGNUM.
gdb/ChangeLog:
* ia64-linux-nat.c (ia64_linux_fetch_register): Add special
handling for r0.

SEGV during AX eval of OP_DOUBLE (unsupported)
To reproduce the problem, simply try the following with any program:
(gdb) maintenance agent-eval 1.0
Critical error handler: process [...] terminated due to access violation
(this is on Windows; on GNU/Linux, the libc copes better)
The problem is quite simple: gen_expr is given an expression that
contains an unrecognized operator (OP_DOUBLE in this case). When that
happens, it tries to report an error with a string image of the operator
in the error message. Conversion of the opcode into a string is done
using op_string which, despite its name, probably is not what the author
was looking for. This function returns NULL for a lot of the opcodes,
thus triggering the crash.
There is a function that corresponds to what we are looking for:
expprint.c:op_name. It was static, though, so I made it non-static,
and used it from ax-gdb.c:gen_expr.
gdb/ChangeLog:
* expression.h (op_name): Add declaration.
* expprint.c (op_name): Remove declaration. Make non-static.
* ax-gdb.c (gen_expr): Use op_name instead of op_string.
