flickcurl: builds failing for macOS 11 and later: implicit function declarations: abort, calloc, malloc, free, atoi

[mascguy (Christopher Nielsen)]

We may simply need to patch the source, to include additional headers like stdlib.h, etc.

Details:

blog.c:43:5: error: call to undeclared library function 'free' with type 'void (void *)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    free(blog->id);
    ^
blog.c:43:5: note: include the header <stdlib.h> or explicitly provide a declaration for 'free'

blog.c:94:29: error: call to undeclared library function 'calloc' with type 'void *(unsigned long, unsigned long)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  blogs = (flickcurl_blog**)calloc(sizeof(flickcurl_blog*), nodes_count+1);
                            ^

blog.c:114:27: error: call to undeclared library function 'malloc' with type 'void *(unsigned long)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
      attr_value = (char*)malloc(attr_len + 1);

        b->needs_password = atoi(attr_value);

These issues are probably already fixed upstream, there just hasn’t been a release in a ​long while.
