[Spice-devel] [PATCH spice-gtk 0/4] Another set of macOS pre-enablement patches

[Christophe de Dinechin]

This patch set eliminates warnings detected by clang with respect
to type alignments. Vittorio Toso had submitted something
similar. In this version, I took into account comments by
Christophe Fergeau regarding how to know which casts were
aligned and which ones were not aligned. I added some
instrumentation to detect the two cases.

The casts that are supposed to be aligned will issue a warning
if data is actually misaligned.

The casts that are known to be misaligned can still be checked
by setting environment variable SPICE_DEBUG_ALIGNMENT=1

(This requires an update spice-common, reference to submodule udpated)

Christophe de Dinechin (4):
 Avoid clang warnings on casts with stricter alignment requirements
 Avoid warning about snprintf on non-Linux platforms
 Remove warning about unused variable when building on macOS
 Add check for macOS, disable ucontext on macOS (deprecated)
