static function overhaul #3538
Here's a script to
... and the associated changes to a bunch of files to cleanup all issues the script detected. I'll subsequently have a go and see if I can add the script to one or more of the travis builds to make sure we detect these mistakes/optimizations before they land.
(I intend so squash all these into a single commit for the changes and one for the script before merging)
urlapi: turn three local-only functions into statics conncache: make conncache_find_first_connection static multi: make detach_connnection static connect: make getaddressinfo static curl_ntlm_core: make hmac_md5 static http2: make two functions static http: make http_setup_conn static connect: make tcpnodelay static tests: make UNITTEST a thing to mark functions with, so they can be static for normal builds and non-static for unit test builds ... and mark Curl_shuffle_addr accordingly. url: make up_free static setopt: make vsetopt static curl_endian: make write32_le static rtsp: make rtsp_connisdead static warnless: remove unused functions memdebug: remove one unused function, made another static
That is functions that are declared global but are not used from outside of the file in which it is declared. Such functions should be made static or even at times be removed. It also verifies that all used curl_ prefixed functions are "blessed"
