Writing of crash dumps were done using unbuffered IO. This
is slow since many small writes are done.
Use a FILE* with an allocated buffer to obtain buffered IO.
I wrote a small test program that created 50000 binaries of 200 bytes
each and then created a crash dump. The crash dumping was an order of
magnitude faster with buffered IO than without.

On little-endian machines, doing &int will give the smallest
byte which is what we want to give to write. But on big-endian
it will give the highest byte, which will always be \000 here
which results in write never doing any writes.
So we have to cast c to an unsigned char before passing it to
write.

Now that stdout can be set as non-blocking by the ttsl driver
we can no longer use putc and friends for the stdout/stderr
streams. Therefore we fallback on write.

Add probes to the virtual machine, except (mostly) the efile_drv.c
driver and other file I/O-related source files.
