  core: Add new parameter ('pv_print_buf_size')

This setting will be useful in case large bodies of text need to be
expanded during a pseudo-variable format printing.  For example:

avp_db_query("SELECT $var(columns) FROM $var(table)", $avp(result));
             ^ before this commit, the output of this format was
	       capped at 1024 bytes

Closes #1659

(cherry picked from commit a977a1c3426c0fbd6bdc2d5f60aff9461c465360)
