Cothread: Workaround for compiler warning

Alas, the valgrind headers trigger a compiler warning, which we suppress
here by marking valgrind.h as a "system header" file.

Cothread: Fix probable syntax error in assembler

Seems that clang is more fussy than gcc about the syntax of the .type
directive, so fix a missing comma.

Cothread: Add mechanism for requesting entire waveform

As ca{get,monitor}(pv, ..., count=0) requests data dependent waveform
length we need a simple mechanism for always requesting the entire
waveform.

Also update the documentation for count.
