* Initialization routine for vim_findfile().
*
* Returns the newly allocated search context or NULL if an error occurred.
*
* Don't forget to clean up by calling vim_findfile_cleanup() if you are done
* with the search context.
*
* Find the file 'filename' in the directory 'path'.
* The parameter 'path' may contain wildcards. If so only search 'level'
* directories deep. The parameter 'level' is the absolute maximum and is
* not related to restricts given to the '**' wildcard. If 'level' is 100
* and you use '**200' vim_findfile() will stop after 100 levels.
*
* 'filename' cannot contain wildcards! It is used as-is, no backslashes to
* escape special characters.
*
* If 'stopdirs' is not NULL and nothing is found downward, the search is
* restarted on the next higher directory level. This is repeated until the
* start-directory of a search is contained in 'stopdirs'. 'stopdirs' has the
* format ";*<dirname>*\(;<dirname>\)*;\=$".
*
* If the 'path' is relative, the starting dir for the search is either VIM's
* current dir or if the path starts with "./" the current files dir.
* If the 'path' is absolute, the starting dir is that part of the path before
* the first wildcard.
*
* Upward search is only done on the starting dir.
*
* If 'free_visited' is TRUE the list of already visited files/directories is
* cleared. Set this to FALSE if you just want to search from another
* directory, but want to be sure that no directory from a previous search is
* searched again. This is useful if you search for a file at different places.
* The list of visited files/dirs can also be cleared with the function
* vim_findfile_free_visited().
*
* Set the parameter 'find_what' to FINDFILE_DIR if you want to search for
* directories only, FINDFILE_FILE for files only, FINDFILE_BOTH for both.
*
* A search context returned by a previous call to vim_findfile_init() can be
* passed in the parameter "search_ctx_arg". This context is reused and
* reinitialized with the new parameters. The list of already visited
* directories from this context is only deleted if the parameter
* "free_visited" is true. Be aware that the passed "search_ctx_arg" is freed
* if the reinitialization fails.
*
* If you don't have a search context from a previous call "search_ctx_arg"
* must be NULL.
*
* This function silently ignores a few errors, vim_findfile() will have
* limited functionality then.
