a4b3a0c955 qopen-in-vm: ensure we can't mistake a non empty file for an empty one 
st_size is off_t, which may be larger than int.

38c0ea3128 qopen-in-vm: fix read overflow 
That one would also send more data to the other VM that what we
intended: the start of the env var data (which in similar code
on my host includes the GPG agent socket path, XDG session cookie,
and more.

The other side expects a fixed size though, so pad with NULs.

Interestingly, the original code was not vulnerable as it was
callocing enough space.

a0f3ce9e93 Hide errors from qubes.WaitForSession 
Especially "Killed" message, which is normal as 'sleep' is signalled with
SIGKILL once session is ready.

6c3c3e717d tar2qfile: use lseek() to skip unwanted data if possible 
When reading from file it is much faster.

3c92cdba22 tar2qfile: use read_all() instead of read() 
read() syscall do not guarantee to read as much data as requested. This
is especially important when reading from pipe - remote end can produce
data slower than we are reading them. Use read_all() helper to always
get requested amount of data.

9b859c9ac5 qubes-rpc: save one syscall on each data block 
read_all/write_all calls set_* on every call, so this can be
noticeable performance improvement.

3c43f20d9e tar2qfile: terminate parsing when all requested files/dirs found 
Assume that all the files of directory are in continuous block (which is
true in case of qvm-backup stream). This will allow to terminate before
getting to the file end - especially useful when only qubes.xml
requested.

8f840e10dc vm-file-editor: add override for mimeinfo *.png entry (#753) 
MIME-info database contains multiple entries for *.png, namely image/png
and image/x-apple-ios-png. The later one doesn't have associated handler
program, but this one is selected by mimeopen tool.

Not sure how this tool should behave in case of multiple matches (IOW is
it a bug in File::MimeInfo perl module used by mimeopen).  Instead of
switching to different tool, which probably will break other files
(check #423), add override for this particular file type.

af03425187 tar2qfile: fix compiler warnings 
Actually one was real bug:
-				current = ustar_rd(fd, &hdr, &buf, &sb);
+				current = ustar_rd(fd, &hdr, buf, &sb);
The others was mostly invalid printf format string.

c9eb50cbe4 suspend: empty default list of modules to unload 
Now dom0 will initiate real suspend process in VMs with PCI devices, so
workaround with unloading modules no longer needed.
Additionally it looks like unloading ehci-pci causes suspend problems on
some hardware (C200 Series Chipset).
