Allow response body callbacks to return an error:

* src/ne_request.h (ne_block_reader): Return error code.

* src/ne_request.c (ne_read_response_block): Fail with -1 if a reader
callback returns an error.

* src/ne_xml.c (ne_xml_parse_v): Return 0 (for the moment).

* src/ne_basic.c (get_to_fd): Return error.

* src/ne_compress.c (gz_reader): Return 0 (mostly), or pass through.

* src/ne_auth.c (auth_body_reader): Return 0.

* test/compress.c (reader): Return error.

* test/request.c (collector): Return 0.
(abortive_reader, abort_reader): New functions.
