virsh: split out virsh.h
Having one .c file include another does not give any compilation benefits; move towards modular .o files by first splitting out reused declarations into a new virsh.h. This patch doesn't try very hard to see which functions are used or not, to make it easier to review the file split. Future patches can further trim the header to be smaller. * tools/Makefile.am (virsh_SOURCES): List new file, and prepare for others. * tools/virsh.c: Split declarations... * tools/virsh.h: ...into new file, and make several functions non-static. * tools/virsh-domain-monitor.c (vshGetDomainDescription): Make non-static.
