Tested build on a minimal Ubuntu 16.04 container image without wget.

The GLUON_ATH10K_MESH must be set to 11s or ibss; when it is not set,
ath10k device images won't be built at all. This also allows us to remove
the BROKEN flag for ath10k devices, as the GLUON_ATH10K_MESH variable is
sufficient to avoid ath10k devices if desired.

Fixes #864

The MR1750 and OM5P-AC devices are based on ath9k SoCs and an external
ath10k chip. All devices which are using ath10k should be marked as broken
due to deficits in their IBSS support.

[Matthias Schiffer: changed the text a bit]

+ added profile for these devices

Generate flashable images for the Archer C7 v2 with current stock firmware
again.

To set the region code, the GLUON_REGION variable must be set to "us" or
"eu" in site.mk or as a make argument.

Fixes #860

Allows weird release numbers, models and site names, and prepares support
for pretty hostnames.

and add documentation

Use the common term; the "Expert Mode" never was a distinct mode of
operation anyways.

Fixes #823
