[Libguestfs] [PATCH nbdkit v2 0/9] curl: Use curl multi interface

[Richard W.M. Jones]

This is a slightly cleaner version of the patch previously posted
here:

Patch #8 is still irreducibly complex, but I can't see an easy way
around that.

I spent more time refining the commands that get passed to the worker
thread so that now there are only two (EASY_HANDLE and STOP), since
all operations can be expressed in terms of just those two commands.

Test & valgrind all pass, and there are no missing features.

Rich.
