Subject: curl: unify pointer names to global config
X-Git-Tag: curl-8_15_0~51
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d516628d14e3cb079f4863f1f36e64c9d4810271;p=thirdparty%2Fcurl.git

curl: unify pointer names to global config

Use 'config' for pointing to a OperationConfig

Use 'global' for pointing to GlobalConfig

Bonus: add config_alloc(), an easier way to allocate + init a new
OperationConfig struct.

Closes #17888
