5d05b9d462 target/arm: Reorganize PMCCNTR accesses
pmccntr_read and pmccntr_write contained duplicate code that was already
being handled by pmccntr_sync. Consolidate the duplicated code into two
functions: pmccntr_op_start and pmccntr_op_finish. Add a companion to
c15_ccnt in CPUARMState so that we can simultaneously save both the
architectural register value and the last underlying cycle count - this
ensures time isn't lost and will also allow us to access the 'old'
architectural register value in order to detect overflows in later
patches.

8c07559fc7 migration: Add post_save function to VMStateDescription
In some cases it may be helpful to modify state before saving it for
migration, and then modify the state back after it has been saved. The
existing pre_save function provides half of this functionality. This
patch adds a post_save function to provide the second half.

2d2a4549cc target/arm: Allow Aarch32 exception return to switch from Mon->Hyp
In U-boot, we switch from S-SVC -> Mon -> Hyp mode when we want to
enter Hyp mode. The change into Hyp mode is done by doing an
exception return from Mon. This doesn't work with current QEMU.

The problem is that in bad_mode_switch() we refuse to allow
the change of mode.

Note that bad_mode_switch() is used to do validation for two situations:

 (1) changes to mode by instructions writing to CPSR.M
     (ie not exception take/return) -- this corresponds to the
     Armv8 Arm ARM pseudocode Arch32.WriteModeByInstr
 (2) changes to mode by exception return

Attempting to enter or leave Hyp mode via case (1) is forbidden in
v8 and UNPREDICTABLE in v7, and QEMU is correct to disallow it
there. However, we're already doing that check at the top of the
bad_mode_switch() function, so if that passes then we should allow
the case (2) exception return mode changes to switch into Hyp mode.

We want to test whether we're trying to return to the nonexistent
"secure Hyp" mode, so we need to look at arm_is_secure_below_el3()
rather than arm_is_secure(), since the latter is always true if
we're in Mon (EL3).

a442fe2f2b sdl: add support for high resolution window icon
Modern desktop environments can render icons at very large sizes,
especially with high DPI screens. Providing a 32x32 pixel bitmap is
nowhere near sufficient anymore.

When displayed in GNOME shell the QEMU icon looks awful, having been
scaled up to at least x4 its base size. This is compounded by the fact
that the BMP file doesn't do transparency, so while we've removed white
pixels, we still have anti-aliased nearly-white pixels which make the
logo look appalling on black backgrounds.

Loading a high resolution PNG icon addresses both problems, but requires
use of the extra SDL2_image library.

67ea954682 ui: fix icon display for GTK frontend under GNOME Shell with Wayland
The icon associated with a GtkWindow is just a hint to window managers
and not all of them will honour it. Some will instead want to show the
icon listed by the .desktop file. The desktop file is located based on
the application ID, which is set using g_set_prgname. QEMU has not
historically provided a desktop file or set its app ID, so it got a
broken icon in GNOME shell, which is now fixed.

a8260d3876 ui: install logo icons to $prefix/share/icons
QEMU currently installs logos to $prefix/share/qemu/ which means no GUI
toolkit or applications can find them by default.

The accepted standards for desktop applications declare that application
logos / icons should be installed under $prefix/share/icons, so use this
directory location.

Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.

The PNGs are rendered from the SVG using inkscape, however, this is not
wired up into the default make rules to avoid requiring inkscape as a
mandatory tool in build systems / developer workstations.

0f645ba16c contrib/rdmacm-mux: fix clang compilation
Fix Commit a5d2f6f877 (contrib/rdmacm-mux: Add implementation
                       of RDMA User MAD multiplexer).

The above commit introduces a new contrib target, adding a global dependency
to libumad library in case pvrdma configuration option is enabled.
Clang forbids it:
    clang-6.0: error: -libumad: 'linker' input unused
              [-Werror,-Wunused-command-line-argument]

Fix by limiting the scope to the rdmacm-mux target itself.

In rdma_rm_get_backend_gid_index(), the 'sgid_idx' is used
to index the array 'dev_res->port.gid_tbl' which size is
MAX_PORT_GIDS. Current the 'sgid_idx' may be MAX_PORT_GIDS
thus cause an off-by-one issue.
