libsigrok.h: Add measured quantity and units used by Radioshack 22-812 

The Radioshack 22-812 can measure parameters such as transistor gain,
dbm, etc. Add those to libsigrok.h.

The SR_UNIT_UNITLESS is for quantities that do not have units. Any
ratio or gain are just factors, whic do not have units. Specifically,
a transistor's gain, or hFE, is a unitless quantity.
