Deregister all callbacks when disconnecting from libvirt.
Deregister all callbacks when we lose or close the connection to libvirt. This fixes a problem where goroutines with outstanding requests waiting for replies would block forever if the libvirt connection dies, whether because disconnect is called, or the libvirt daemon crashes or restarts.
- Marked all the remaining old APIs from before the code-generator as
deprecated. These will be removed from the go-libvirt library as soon as
we're moved all the DO code over to use the generated APIs.
- Consolidated a couple of APIs whose implementation was split into
multiple files.
- Removed a couple of Migration-related calls we're no longer using.
* prevent connection write collisions
When multiple calls are made on the same connection, it's possible for
the writes to collide with each other. This adds a write mutex when
communicating with the libvirt daemon.
- Add a yacc-based parser and a hand-written lexer to read the
remote_protocol.x file from libvirt's sources.
- Use the new parser to generate the constants used to communicate with
libvirt.
This fixes a bug in truncated response payload handling. Payloads
requiring more than one call to `Read()` were overwiting the previous
Read()'s buffer contents. Because we know the response payload size, we
can simply call `io.ReadAll()` rather than looping over calls to
`Read()`.
This splits out the mock libvirt server for testing within
other packages. Constants from the main libvirt package
have been moved to a separate package, constants, for shared access.
