nginx: src/http/modules/ngx_http_gzip_filter

annotate src/http/modules/ngx_http_gzip_filter_module.c @ 5876:973fded4f461

Gzip, gunzip: flush busy buffers if any. Previous code resulted in transfer stalls when client happened to read all the data in buffers at once, while all gzip buffers were exhausted (but ctx->nomem wasn't set). Make sure to call next body filter at least once per call if there are busy buffers. Additionally, handling of calls with NULL chain was changed to follow the same logic, i.e., next body filter is only called with NULL chain if there are busy buffers. This is expected to fix "output chain is empty" alerts as reported by some users after c52a761a2029 (1.5.7).
