70deec767a DEV: coccinelle: add endp_flags.cocci 
This one turns the various forms of "endp->flags <op> value" to their
se_fl_<op>(cs) equivalent. That's basically the same as the previous
one except that it acts on the stream endpoint itself instead of the
conn_stream.

their sc_ep_<op>(cs) equivalent.

14abfb61fb DEV: coccinelle: Add a new pattern to ist.cocci 
This was previously ignored in "DEV: coccinelle: Fix incorrect replacement in ist.cocci",
but is now properly replaced by a simple `ist()` call.

99f47377c8 DEV: coccinelle: Fix incorrect replacement in ist.cocci 
We must not use `ist2()` if the value of `i.len` is derived from the value of
`i.ptr`:

    i.ptr = "foo";
    i.len = strlen(i.ptr);

64755bf856 Revert "DEV: coccinelle: Add rule to use chunk_istcat() instead of chunk_strncat()" 
This reverts commit b9656e48377a9e5359494bce6a413a9915c8f74b. It's
not needed anymore since 49b0482ed ("CLEANUP: chunk: remove misleading
chunk_strncat() function").

b9656e4837 DEV: coccinelle: Add rule to use chunk_istcat() instead of chunk_strncat() 
This replaces `chunk_strncat()` with `chunk_istcat()` if the parameters are the
ist's `.ptr` and `.len`.

755d2419a4 DEV: coccinelle: Add rule to use chunk_istcat() instead of chunk_memcat() 
This replaces `chunk_memcat()` with `chunk_istcat()` if the parameters are the
ist's `.ptr` and `.len`.

9b80a6ca8f DEV: coccinelle: Add rule to use isttrim() where possible 
This replaces `if (i.len > e) i.len = e;` by `isttrim(i, e)`.

958f50454a DEV: coccinelle: Add rule to use istend() where possible

ef00c533e1 DEV: coccinelle: Add rule to use istnext() where possible 
This matches both `istadv(..., 1)` as well as raw `.ptr++` uses.

e6c04507d8 DEV: coccinelle: Add realloc_leak.cocci 
This coccinelle patch finds locations where the return value of `realloc()` is
assigned to the pointer passed to `realloc()`. This calls will leak memory if
`realloc()` returns `NULL`.

02fa646a37 DEV: coccinelle: Add bug_on.cocci 
This replaces an if + ABORT_NOW() by BUG_ON(). It might change behavior,
because BUG_ON will result in a no-op if not enabled.
