Subject: Add uv_req_get_data() and uv_req_set_data() compatibility shims
X-Git-Tag: v9.17.14~13^2~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f752840db39eaceb93094e56a378444fba676794;p=thirdparty%2Fbind9.git

Add uv_req_get_data() and uv_req_set_data() compatibility shims

The uv_req_get_data() and uv_req_set_data() functions were introduced in
libuv >= 1.19.0, so we need to add compatibility shims with older libuv
versions.
