Add various widely useful "IWYU pragma" annotations, such as - Common header files such as c.h, postgres.h should be "always_keep". - System headers included in c.h, postgres.h etc. should be considered "export". - Some portability headers such as getopt_long.h should be "always_keep", so they are not considered superfluous on some platforms. - Certain system headers included from portability headers should be considered "export" because the purpose of the portability header is to wrap them. - Superfluous includes marked as "for backward compatibility" get a formal IWYU annotation. - Generated header included in utils/syscache.h is marked exported. This is a very commonly used include and this avoids lots of complaints. Discussion: https://www.postgresql.org/message-id/flat/9395d484-eff4-47c2-b276-8e228526c8ae@eisentraut.org
