Replace the recursive glob matcher with an iterative O(pattern*string)
dynamic program. The old recursion explored exponentially many paths for
overlapping '*'/'**' wildcards (e.g. '*a*a*...*b' against a long run of
'a'), a CPU DoS reachable from --exclude/--include patterns and
.rsync-filter. A differential fuzz against the original matcher confirms
identical results. Doc: has_path_traversal() is a lexical '..' check only.
Add utils_getdelim_bounded(): a getdelim-style reader that never allocates
beyond UTILS_MAX_LINE_LEN, used to cap untrusted list/filter line reads.
Tests: pathological glob completes quickly; bounded reader returns EFBIG on
an over-long record.
- Fix transport_tcp.c: initialize server->ssl_ctx to NULL
(prevents SSL_CTX_free on garbage when server_create_tls fails)
- Fix test_transport_tcp.c: client_create now sets fd=-1, family=AF_UNSPEC
- Fix test_transport_tcp.c: server address family may be AF_INET or AF_INET6
- Fix test_file_sendfile.c: send_path=false protocol includes file_type prefix
