Add plugin API for processing plugin-added input files.

Browse Source 
Gold plugins may wish to further process an input file added by a plugin. For
example, the plugin may need to assign a unique segment for sections in a
plugin-generated input file. This patch adds a plugin callback that the linker
will call when reading symbols from a new input file added after the
all_symbols_read event (i.e. an input file added by a plugin).

	* plugin-api.h: Add plugin API for processing plugin-added
