Add a parallel set of APIs to the domain builders to allow images and
ramdisks to be passed via buffer, rather than via file. This allows
usage of the underlying domain building routines in "file-challenged"
enviroments.
Specifically, xc_linux_build_mem is the buffer oriented version of the
file-oriented xc_linux_build. Likewise, xc_hvm_build_mem is the
buffer oriented analog of the file based xc_hvm_build.
