dtc: cpp co-existence: allow names starting with # to be escaped
The device tree language as currently defined conflicts with the C pre-
processor in one aspect - when a property or node name begins with a #
character, a pre-processor would attempt to interpret it as a directive,
fail, and most likely error out.
This change allows a property/node name to be prefixed with \. This
prevents a pre-processor from seeing # as the first non-whitespace
character on the line, and hence prevents the conflict. \ was previously
an illegal character in property/node names, so this change is
backwards compatible. The \ is stripped from the name during parsing
by dtc.
