417131fb9a HACKING: Update status of format checking
Hopefully all functions with printf like arguments now use format checking.

This was tested with default build configuration on linux
and windows hosts (including some cross compilations),
so chances are good that there remain few (if any) functions
without format checking.

Therefore the last comment in HACKING is no longer valid but misleading.

c53af37f37 vnc: fix a memory leak in threaded vnc server
VncJobQueue's buffer is intended to be used for
as the output buffer for all operations in this queue,
but unfortunatly.

vnc_async_encoding_start() is in charge of setting this
buffer as the current output buffer, but
vnc_async_encoding_end() was not writting the changes back
to VncJobQueue, resulting in a big and ugly memleak.

89d2d3af51 slirp: Remove some type casts caused by bad declaration of x.tp_buf
x.tp_buf was declared as a uint8_t array, but always used as

The patch includes these changes:

* Fix declaration of x.tp_buf and remove all type casts.

The frequency is pre-calculated every 500ms, based on the last 10
