On GLES hosts, BGR* resources are manually swizzled to RGB* internal
format on creation and swizzled back to BGR* format on readback.
For small transfers, iovec data is directly passed to the host driver
without staging in a temp buffer first. When swizzling for BGR*
resources, this modifies the persistend iovec buffer when it should
remain in the user-provided format. So we force temp buffers for all
iovec transfers on BGR* resources on GLES hosts to fix this.

Since externally-stored BGRA resource buffers must remain with
BGRA byte ordering, there are several special cases in the custom
blitter that need to be handled, based on the source and destination
resource formats, as well as the views requested on each by the caller.
This change gives the caller more control over the swizzling operation
to perform during the shader-based blit, so the caller can reconcile the
special cases more concisely.

BGRA resources that use external storage (EGL image, GBM)
must keep the data store in the BGRA byte-order, while
producing the correct results when used within the host's
GL or GLES API. To maintain compatability of BGRA resources
with features such as gamma correction, texture views, and
multisampled rendering, virglrenderer swizzles BGRA texture
data to RGBA and passes GL_RGBA to the host API, then swizzles
the RGBA data back to BGRA on readout.
With external storage, virglrenderer no longer has complete
control over buffer accesses, with the possibility that buffers
will be written to and read out by other processes, such as the
display compositor. Under these circumstances, we need to emulate
the external buffer format when using it with the host rendering
API such that data is accessed from the backing buffer as RGBA
and written back as BGRA.

BGRA emulation was added to address rendering artifacts when GL guest
apps are run on a GLES host with virglrenderer's use_gles == true.
Due to tenuous compatibility of EXT_texture_format_BGRA8888 with
gamma correction (sRGB formats/views) and multisampled rendering on
GLES hosts, it is best to represent BGR* resourcs with RGB* internal
format and add necessary byte re-ordering on to/from transfers instead.
Note, however, that removing the existing BGR* emulation will cause
problems for externally stored resources such as EGL images, and GBM
allocated buffers, which may actually be stored with BGR* byte-order.
This is addressed in the commits immediately following this one.
