b21ee1fc42 vm-file-editor: remove temporary file on exit 
This allows editing the same file more than once on the
same (non disposable) VM, as well as keeping /tmp from
ballooning indefinitely.

7953af970d backups: fix buffer overflow in tar2qfile 
Buffer for directory headers history was too small. This can be
exploitable by some attacker capable of controlling backup stream, but
it isn't any security problem. We don't assume this part of backup
system to be trusted, the attacker can at most prevent user from
restoring some data, but will neither gain access to them, or compromise
any other Qubes component. This is equivalent to bug in any other tool
used in backup vm (like FTP client) and the Qubes backup system is
designed specifically to minimize impact of such bugs.

df7c431d0b qfile-utils: do not write a random extra byte 
readlink(2) does not write a terminating NUL, and the read side
will already place a NUL after whatever it receives.
While it seems odd that this would be buggy (ie, synlinks on
the ohter side would be pointing to the wrong filename, though
I guess if we're lucky and the stack had a 0 byte at the right
place, symlink(2) would do what was expected), my reading of
the code tells me this patch is right. Needs testing to double
check.

c171f47ba8 vm-file-editor: put temporary files in per domain subdirectories 
This avoids the possibility that incoming files may match
an existing file in /tmp (whether from the target VM, or a
third VM that's also sent a file for editing), as well as
possible file leaks between domains.

11b8f9be20 vm-file-editor: fix potential buffer overflow

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.

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.

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.

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).
