wireshark: use cmake, update to latest trunk

cmake is faster, let's use that instead of autofoo. While at it,
use a separate build dir as recommended for cmake.

Note: run/ output directory has recently entered the repository.
upower: remove

Outdated, I am now using repo packages anyway.
linux-custom: bump to v3.13.1

Previous uncommitted Linux version: v3.13-rc7-87-g21e20e2

Config changes:
- MMC is a module now (so it can be unloaded to prevent a memleak).
linux-custom: bump to 3.13.2

Running since 8 February 2014, the hotplug stuff was enabled to
investigate an issue (which turned out to be an issue with
CONFIG_HOTPLUG_PCI_ACPI).
linux-custom: bump to 3.14-rc5

This disables the PCI hotplug config again.
wireshark: update to devel version

The actual package has wireshark commit
04d950130624c14ac8af39c621f69851d8088ed6 ("Add capture file
reader/writer support for Lua so scripts can implement new capture file
formats.") backed out because of a compilation error (that got fixed
later that day). It also includes two USB fixes from me (HID descriptor
parsing, show bytes for setup data).
linux-custom: bump to v3.14-rc7-33-g8878439

"Interesting" changes: warning gone when Logitech Unifying USB receiver
gets removed.
