block: purge s->aligned_buf and s->aligned_buf_size from raw-posix.c

The aligned_buf pointer and aligned_buf size are no longer used in
raw_posix.c, so remove all references to them.

block: move aio initialization into a helper function

Move AIO initialization for raw-posix block driver into a helper function.

In addition to just code motion, the aio_ctx pointer is checked for NULL,
prior to calling laio_init(), to make sure laio_init() is only run once....

block: do not parse BDRV_O_CACHE_WB in block drivers

Block drivers should ignore BDRV_O_CACHE_WB in .bdrv_open flags,
and in the bs->open_flags.

This patch removes the code, leaving the behaviour behind as if
BDRV_O_CACHE_WB was set.

block: use BDRV_O_NOCACHE instead of s->aligned_buf in raw-posix.c

Rather than check for a non-NULL aligned_buf to determine if
raw_aio_submit needs to check for alignment, check for the presence
of BDRV_O_NOCACHE in the bs->open_flags.

block/curl: Fix wrong free statement

Report from smatch:
block/curl.c:546 curl_close(21) info: redundant null check on s->url calling free()

The check was redundant, and free was also wrong because the memory
was allocated using g_strdup.

stream: complete early if end of backing file is reached

It is possible to create an image that is larger than its backing file.
Reading beyond the end of the backing file produces zeroes if no writes
have been made to those sectors in the image file.

This patch finishes streaming early when the end of the backing file is...
