Focusing just on sysinfo output. The new virBufferIndent*
functions allow us to shave off quite a few lines of code.
* src/util/sysinfo.h (virSysinfoFormat): Alter signature.
* src/util/sysinfo.c (virSysinfoFormat, virSysinfoBIOSFormat)
(virSysinfoSystemFormat, virSysinfoProcessorFormat)
(virSysinfoMemoryFormat): Change indentation parameter.
* src/conf/domain_conf.c (virDomainSysinfoDefFormat)
(virDomainDefFormatInternal): Adjust callers.
* src/qemu/qemu_driver.c (qemuGetSysinfo): Likewise.
