João Valverde c5a19582e4 epan: Convert to use stdio.h from GLib
Replace:
    g_snprintf() -> snprintf()
    g_vsnprintf() -> vsnprintf()
    g_strdup_printf() -> ws_strdup_printf()
    g_strdup_vprintf() -> ws_strdup_vprintf()

This is more portable, user-friendly and faster on platforms
where GLib does not like the native I/O.

Adjust the format string to use macros from intypes.h.

Moshe Kaplan e16166a74c Detect and replace bad allocation patterns
Adds a pre-commit hook for detecting and replacing
occurrences of `g_malloc()` and `wmem_alloc()` with
`g_new()` and `wmem_new()`, to improve the
readability of Wireshark's code, and
occurrences of
`g_malloc(sizeof(struct myobj) * foo)`
with
`g_new(struct myobj, foo)`
to prevent integer overflows

Also fixes all existing occurrences across
the codebase.

Dario Lombardo 1b5624a718 plugin_if: don't allocate memory and cast it instead.
Glib hash table can use integers as pointer by casting them
using GINT_TO_POINTER. This prevents alloc/free of memory.

Roland Knall acc581081e Plugin Interface: Add GUI callbacks
Rename ext_menubar to a more appropriate plugin_if.

 External menus can be implemented by plugins to present
 additional menus for deep-packet analysis. One side-effect
 of such menus being implemented as plugins is, that they
 are being executed in different threads and therefore can
 only use limited access to the main GUI. Also, there is
 no safe cross-gui (GTK and Qt) way for many features.

 This patch implements a first functionality, by which a
 plugin implemented using ext_menubar can apply a display
 filter to the main view.

 For now the implementation supports filtering, as well as
 saving a preference.
