Instead of trying all PCI devices by a specific PCI driver, now the device or
the device class can be limited to the one actually supported by the specific
driver.
As iPXE header files are not C++ compatible, the implementation missed
proper include directives. For example, alloc_memblock() had a wrong
signature, which was not detected. Now, C wrapper functions are
implemented using a local API to the C++ backend.
Related to #593.
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.
Related to issue #526.
