cutils: Make strtosz & friends leave follow set to callers
strtosz() & friends require the size to be at the end of the string,
or be followed by whitespace or ','. I find this surprising, because
the name suggests it works like strtol().
The check simplifies callers that accept exactly that follow set
slightly. No such callers exist.
The check is redundant for callers that accept a smaller follow set,
and thus need to check themselves anyway. Right now, this is the case
for all but one caller. All of them neglected to check, or checked
incorrectly, but the previous few commits fixed them up.
Finally, the check is problematic for callers that accept a larger
follow set. This is the case in monitor_parse_command().
Fortunately, the problems there are relatively harmless.
monitor_parse_command() uses strtosz() for argument type 'o'. When
the last argument is of type 'o', a trailing ',' is diagnosed
differently than other trailing junk:
(qemu) migrate_set_speed 1x
invalid size
(qemu) migrate_set_speed 1,
migrate_set_speed: extraneous characters at the end of line
A related inconsistency exists with non-last arguments. No such
command exists, but let's use memsave to explore the inconsistency.
The monitor permits, but does not require whitespace between
arguments. For instance, "memsave (1-1)1024foo" is parsed as command
memsave with three arguments 0, 1024 and "foo". Yes, this is daft,
but at least it's consistently daft.
If I change memsave's second argument from 'i' to 'o', then "memsave
(1-1)1foo" is rejected, because the size is followed by an 'f'. But
"memsave (1-1)1," is still accepted, and duly saves to file ",".
We don't have any users of strtosz that profit from the check. In the
users we have, it appears to encourage sloppy error checking, or gets
in the way. Drop the bothersome check.

fractions are no longer rejected, because we go to switch case 'M' on

Define a state callback and make that generate chardev open/close events when

the code ignores these events for a spicevmc with a subtype of vdagent, this
subtype specific knowledge is undesirable, but unavoidable for now, see:
http://lists.freedesktop.org/archives/spice-devel/2011-July/004837.html
2) This code deliberately sends the events immediately rather then from a
bh. This is done this way because:
a) There is no need to do it from a bh; and
b) Doing it from a bh actually causes issues because the spice-server may send
data immediately after the open and when the open runs from a bh, then
qemu_chr_be_can_write will return 0 for the first write which the spice-server
does not expect, when this happens the spice-server will never retry the write

rtl8139: Fix invalid IO access alignment
This patch makes iPXE work with the rtl8139 emulation. The rtl8139
driver in iPXE issues a 16bit access on the ChipCmd register
(offset 0x37) to check the status of the rx buffer. The offset of the
ioport access was getting fixed up to 0x36 in qemu, causing the value
read in iPXE to be invalid.
This fixes an issue with iPXE reporting timeouts during TFTP transfers.
Reposting this here because it is trivial enough and the original post
on qemu-devel didn't attract much attention.
Also, the inw() which was causing the issue has been replaced with an
inb() in upstream iPXE:

While PIE reduces performance and relro increases load time, it

block: allow migration to work with image files (v3)
Image files have two types of data: immutable data that describes things like
image size, backing files, etc. and mutable data that includes offset and
reference count tables.
Today, image formats aggressively cache mutable data to improve performance. In
some cases, this happens before a guest even starts. When dealing with live
migration, since a file is open on two machines, the caching of meta data can
lead to data corruption.
This patch addresses this by introducing a mechanism to invalidate any cached
mutable data a block driver may have which is then used by the live migration
code.
NB, this still requires coherent shared storage. Addressing migration without
coherent shared storage (i.e. NFS) requires additional work.
