doc: updated github links to reflect recent changes.
fixed a misleading error message.
bugfix: the "unknown option for echo_subrequest_async" error was thrown when nginx variables was used in both the method argument and url argument of the echo_subrequest* directives (and etc). thanks Utkarsh Upadhyay for the report in #34.
doc: bumped version to 0.54 and states that we work with nginx 1.7.2.
bugfix: reading $echo_client_request_headers could lead to buffer overflow due to misuse of r->header_end while modules like ngx_fastcgi and ngx_proxy can change r->header_end to point to buffers of their own.
style: minor tweaks.
bugfix: reading $echo_client_request_headers would return garbled data when LF instead of CRLF is used as the line terminator in the original header.
doc: added a Known Issues section.
doc: bumped version to 0.55.
bugfix: create_loc_conf did not return NULL on error. thanks Markus Linnala for the patch in #35.
tests: updated test suite according to the latest changes in Test::Nginx::Socket.
doc: release v0.56.
bugfix: $echo_client_request_headers: we might change nginx's internal buffer pointers, which might cause bad side-effects.
util/build.sh: no longer add luajit lib to RPATH.
refactor: $echo_client_request_headers: simplified the implementation.
bugfix: $echo_client_request_headers: buffer overflow and the "buffer error" exception might happen for massively pipelined downstream requests.
updated the LICENSE file to match README.
bumped version to 0.57.
