qemu-io: Rework alloc command
The alloc command in qemu-io is mostly useless currently. Instead of doing asingle call to bdrv_is_allocated, we must call bdrv_is_allocated in a loopuntil we have found out for each requested sector if it is allocated or not...
qemu-io: reject invalid pattern
Replace the use of atoi which is used for pattern parsing currently withstrtol. Atoi won't parse sedecimal pattern values (it always returns 0),but qemu-iotests use such pattern values. Also reject every patternthat is not a unsigned char as we pass the pattern to memset which...
qemu-io: Implement bdrv_load_vmstate/bdrv_save_vmstate
The load_vmstate and save_vmstate functions are implemented as avariation of the normal read/write operation, enabled by the -b option.This is the same mechanism as is used to switch from read/write to...
qemu-io: use BDRV_O_FILE to implement the growable open option
Instead of doing our own check for protocols which fails because raw isn'tformally a protocol but special cased in find_protocol specify the BDRV_O_FILEoption to use the same code as bdrv_file_open does....
qemu-io: small cleanups for the aio code
Address a couple of review comments from Kevin.

qemu-io: better input validation for vector-based commands
Fix up a couple of issues with validating the input of the variouslength arguments for the vectored I/O commands:
- do the alignment check on each length instead the always 0 count argument - use a long long varibale for the cvtnum return value so that we can check...
qemu-io: add flag to mark files growable
Add a -g flag to the open command and the main qemu-io command line toallow opening a file growable. This is only allowed for protocols,mirroring the limitation exposed through bdrv_file_open.

qemu-io: fix memory leak
qemu-io leaks the request buffer whenever the read or write function isn'texecuted completely down the "normal" code path.
[hch: also fix the aio and vectored variants the same way]

Fix dump output in qemu-io.
The dump output was not nicely formatted for byteslarger than 0x7f, because signed values expanded tosizeof(int) bytes. So for example 0xab did not printas "ab", but as "ffffffab".
I also cleaned the function prototype, which avoids...
qemu-io: Fix spelling in help message.

qemu-io: add aio read/write/flush commands
Add commands to exercise asynchronous reads/writes and to flush alloutstanding aio commands. Commands to exercise aio cancellations willfollow in a separate patch.
Workaround compiler warnings at -O1

qemu-io: Optionally verify only part of read data
There are reasonable test cases where a read must span areas that are notuniformly filled with one pattern but contains several parts. This makes -Puseless for them currently.
Introducing additional options which determine the part of the read data that...
qemu-io: Verify read data by patterns (Kevin Wolf)
This patch adds a -P option to read and readv which allows to compare the readdata to a given pattern. This can be used to verify data written by write -P.

qemu-io: Fix handling of bdrv_is_allocated() return value (Kevin Wolf)
bdrv_is_allocated() returns a boolean which indicates if the offset isallocated, not 0 on success and everything else is an error.
a couple of qemu-io fixes (Christoph Hellwig)
Fix two stupid bugs that I forgot to push out:
- qiov->size already is in bytes, no need to shift it - actually use the supplied patter in the writev command
Add files not included in previous commit.
