displaced_step_closure is a type defined in multiple -tdep.c files.
Trying to xfree it from the common code (infrun.c) is a problem when we
try to poison xfree for non-POD types. Because there can be multiple of
these types in the same build, this patch makes a hierarchy of classes
with a virtual destructor. When the common code deletes the object
through a displaced_step_closure pointer, it will invoke the right
destructor.
The amd64 used a last-member array with a variable size. That doesn't
work with new, so I changed it for an std::vector. Other architectures
which used a simple byte buffer as a closure now use a shared
buf_displaced_step_closure, a closure type that only contains a
gdb::byte_vector.
Reg-tested on the buildbot.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

Most tdep/nat files are named:
<cpu>-<os>-tdep.c
<cpu>-<os>-nat.c
A few files do not respect this scheme. This patch renames them so that
they are consistent with the rest of the files. It builds fine with
--enable-targets=all, but that doesn't test the nat files. I can only
hope that my grep skill is good enough.

Field syscall_next_pc in struct gdbarch_tdep was to calculate the
next pc of syscall instruction. On linux target, syscall_next_pc
is set to arm_linux_syscall_next_pc, to do linux specific things.
However, after we have struct arm_get_next_pcs_ops, we can do the
same thing in struct arm_get_next_pcs_ops field syscall_next_pc,
so syscall_next_pc in struct gdbarch_tdep is not needed any more.

This patch teaches GDBServer how to software single step on ARM
linux by sharing code with GDB.
The arm_get_next_pcs function in GDB is now shared with GDBServer. So
that GDBServer can use the function to return the possible addresses of
the next PC.
A proper shared context was also needed so that we could share the code,
this context is described in the arm_get_next_pcs structure.
Testing :
No regressions, tested on ubuntu 14.04 ARMv7 and x86.

This patch is in preparation for software single step support on ARM in
GDBServer. It refactors arm_*_software_single_step and sub-functions to
use regcache instead of frame to access registers so that the code can be
shared more easily between GDB and GDBServer.
Note also that since the intention is at some point to get rid of frame
completely in that function, memory reads have also been replaced by
read_memory_unsigned_integer rather than get_frame_memory_unsigned.
No regressions, tested on ubuntu 14.04 ARMv7 and x86.

This patch is to remove the global variable arm_linux_vfp_register_count
from arm-linux-nat.c. This global variable is set when native gdb
looks for the right target description according HWCAP. However,
'struct gdbarch_tdep' has already had a field have_vfp_registers, which
is a boolean about whether target has vfp registers or not. This
patch converts this boolean field to a numeric counter to replace
global variable arm_linux_vfp_register_count.
