Subject: conf: eliminate hardcoded indentation in capabilities xml
X-Git-Tag: v1.2.3-rc1~218

conf: eliminate hardcoded indentation in capabilities xml

There were a lot of changes here, but all very mechanical. For some
reason, the virBufferPtr had been named "xml" instead of "buf" in this
file, so since the indentation changing touched almost every line
using the buffer, I took this chance to change its name for "buf" for
consistency with every other file.
