Before this patch curl code was redefining `getaddrinfo` and `freeaddrinfo` system symbols to plug in its debug wrappers. This was causing pains to avoid applying the redefinitions to system headers defining these functions, and to the local debug wrappers. Especially in unity builds. It also required workarounds for systems where these symbols are already macros. Introduce curl-namespaced macros for these functions and use them. This allows to drop all workarounds and makes it work in all envs, local targets and unity/bundle combinations. Also drop GHA/windows workaround and use the same unity batch across all jobs.

/*
|
|
* Nasty internal details ahead...
|
|
*
|
|
* File curl_memory.h must be included by _all_ *.c source files
|
|
* that use memory related functions strdup, malloc, calloc, realloc
|
|
* or free, and given source file is used to build libcurl library.
|
|
* It should be included immediately before memdebug.h as the last files
|
|
* included to avoid undesired interaction with other memory function
|
|
* headers in dependent libraries.
|
|
*
|
|
* There is nearly no exception to above rule. All libcurl source
|
|
* files in 'lib' subdirectory as well as those living deep inside
|
|
* 'packages' subdirectories and linked together in order to build
|
|
* libcurl library shall follow it.
|
|
*
|
|
* File lib/strdup.c is an exception, given that it provides a strdup
|
|
* clone implementation while using malloc. Extra care needed inside
|
|
* this one.
|
|
*
|
|
* The need for curl_memory.h inclusion is due to libcurl's feature
|
|
* of allowing library user to provide memory replacement functions,
|
|
* memory callbacks, at runtime with curl_global_init_mem()
|
|
*
|
|
* Any *.c source file used to build libcurl library that does not
|
|
* include curl_memory.h and uses any memory function of the five
|
|
* mentioned above will compile without any indication, but it will
|
|
* trigger weird memory related issues at runtime.
|
