The datatype.c object checks could result in a message like:
error: invalid connection pointer in no connection
This consolidates all clients of this message to have uniform contents:
error: invalid connection pointer in someFunc
Note that virCheckConnectReturn raises an error immediately; in
datatypes.c, where we don't need to raise the error (but instead
just leave it in the thread-local setting), we use
virCheckConnectGoto and the cleanup label instead. Then, for
consistency in that file, all subsequent error messages are
touched to also use the cleanup error label.
* src/datatypes.h (virCheckConnectReturn)
(virCheckConnectGoto): New macros.
* src/datatypes.c: Use new macro.
* src/libvirt-qemu.c (virDomainQemuAttach): Likewise.
(virLibConnError): Delete unused macro.
* src/libvirt-lxc.c (virLibConnError): Likewise.
* src/libvirt.c: Use new macro throughout.
* docs/api_extension.html.in: Modernize documentation.
