g_get_charset, g_get_filename_charsets, g_strerror, g_get_home_dir all
return a const char pointer. get_global_random is internally called by
g_random_int, g_random_int_range, etc.
On Arch Linux with glibc 2.26-11 and glib2 2.56.0+7+g66948ae23-1,
"call_init" is not visible in the stack trace, so replace it by "...".
It also has "possibly lost" entries due to GLib types initialization
(gobject_init -> _g_enum_types_init). Finally "g_private_set" internally
leaks after calling "g_private_get_impl".

Valgrind considers the "cpuid" instruction to always depend on inputs from eax
and ecx, even though it's only a subset of values of eax for which ecx is
relevant. If ecx is undefined when cpuid is executed, the outputs of cpuid
will be considered undefined.
Instead of suppressing the resulting uninitialised-value warning (the
suppression for which is now out-of-date anyway, now that
register_all_protocols is moved to a worker thread), let's simply set ecx to
zero in ws_cpuid.
Testing done: Built Wireshark on Linux amd64. Before this change, running
"tools/valgrind-wireshark.sh ./test/captures/dhcp.pcap" with
valgrind-3.12.0.SVN on Debian 9.4 amd64 would yield the following Valgrind
error:
==2416== Thread 2:

With the change, the above message is gone. Inspected the disassembly of
function ws_cpuid, and it looks sane -- just an added "xor ecx, ecx" at the
top.

The fuzzbot has been upgraded, so hopefully this is no longer necessary.
