gitignore: anchor all ignored names
by default, patterns/names in .gitignore are applied
recursively to all subdirectories. So any name mentioned
in .gitignore is ignored in all subdirectores. This is good
for, say. object files (*.o), but not good for particular
names which should be ignored only in one directory. For
example, qemu-img.1 file is generated in the top directory,
and it should be ignored only there, not in some subdir.
At first, this might not matter much, but we have lots of
examples already where it actually does not help at all.
For example, top-level .gitignore ignores a file/dir named
"patches" (which is very questionable by itself), but it
is applied recursively, so git also ignores, for example,
debian/patches/ which should not be ignored.
So anchor all the names where appropriate. .gitignore
should be cleaned up further, which will be addressed in
a subsequent patch.

memory: fix limiting of translation at a page boundary
Commit
360e607 (address_space_translate: do not cross page boundaries,
2014-01-30) broke MMIO accesses in cases where the section is shorter
than the full register width. This can happen for example with the
Bochs DISPI registers, which are 16 bits wide but have only a 1-byte
long MemoryRegion (if you write to the "second byte" of the register
your access is discarded; it doesn't write only to half of the register).
Restrict the action of commit
360e607 to direct RAM accesses. This
is enough for Xen, since MMIO will not go through the mapcache.

So add similar field to DeviceClass so it could be reused

the block driver (which includes RMW data and has therefore potentially
been rounded to alignment boundaries) is fully covered by the
overlap_{offset,size} fields of the associated BdrvTrackedRequest.

block: Fix memory leaks in bdrv_co_do_pwritev()

calls leaked head_buf or tail_buf, respectively. This fixes the memory

raw: Fix BlockLimits passthrough
raw copies over the BlockLimits of bs->file during bdrv_open().
However, since commit
d34682cd it is immediately overwritten during
bdrv_refresh_limits(). This caused all fields except for
opt_transfer_length and opt_mem_alignment (which happen to be correctly
inherited in generic code) to be zeroed.
Move the BlockLimit assignment to a .bdrv_refresh_limits() callback to
make it work again for all fields.

qcow2: check for NULL l2meta
In the case of a metadata preallocation with a large cluster size,
qcow2_alloc_cluster_offset() can allocate nothing and returns a
NULL l2meta. This patch checks for it and link2 l2 with only valid
l2meta.
Replace 9 and 512 with BDRV_SECTOR_BITS, BDRV_SECTOR_SIZE
respectively while at the function.

qcow2: fix offset overflow in qcow2_alloc_clusters_at()
When cluster size is big enough it can lead to an offset overflow
in qcow2_alloc_clusters_at(). This patch fixes it.
The allocation is stopped each time at L2 table boundary
(see handle_alloc()), so the possible maximum bytes could be
2^(cluster_bits - 3 + cluster_bits)
cluster_bits - 3 is used to compute the number of entry by L2
and the additional cluster_bits is to take into account each
clusters referenced by the L2 entries.
so int is safe for cluster_bits<=17, unsafe otherwise.

qcow2: remove n_start and n_end of qcow2_alloc_cluster_offset()
n_start can be actually calculated from offset. The number of
sectors to be allocated(n_end - n_start) can be passed in in
num. By removing n_start and n_end, we can save two parameters.
The side effect is there is a bug in qcow2.c:preallocate() that
passes incorrect n_start to qcow2_alloc_cluster_offset() is
fixed. The bug can be triggerred by a larger cluster size than
the default value(65536), for example:
./qemu-img create -f qcow2 \
-o 'cluster_size=131072,preallocation=metadata' file.img 4G
