This is an implementation which doesn't have undefined behavior
problems. It casts correctly that calculations are don in the correct
integer space. Also the naming is less confusing than what we have in
byteorder.h.

Add new for_selftest option to SAMBA_BINARY() and SAMBA3_BINARY()
This allows us to be much more consistent (at least in the core Samba)
and documents clearly why the binary should not be installed.
Not modified are
- test_lp_load
- notifyd-tests
- gendrandperf
- test* from examples/libsmbclient
- dbwrap_torture
- split_tokens
- locktest2
- msgtest
- msg_sink
- msg_source
- versiontest
- rpc_open_tcp
- test_headers
As these are not tested in selftest so any change would also be
untested. Of course they probably should be added in a different
MR.
Also not modified (because they are not tests, nor part of the
build system) are:
- smb2mount
- notifydd
- log2pacp
- debug2html
- smbfilter
- destroy_netlogon_creds_cli
- spotlight2*
- tevent_glib_tracker
These do however appear to be untested.
For now, the source4 forked client tools are left unchanged:
- smbclient4
- nmblookup4
Finally, the heimdal binaries are left as install=False as
they are either part of the build system or end-user tools
that we just don't want to install. These are however tested.
The motivation is commit like c34ec003b7
and da87fa998a, which are both totally
correct but are not needed if the selftest is not run on MacOS.
There are likely other platforms or build environments where building
our test binaries is more pain than valuable, see for example also

Print the talloc full report into a FILE*. talloc itself provides a

For standalone ctdb builds, a samba-util-core dependency is added,
without corresponding systemd libraries, which are needed when
become_daemon.c is built --with-systemd. This results in:
default/lib/util/become_daemon_20.o: In function `daemon_status':
become_daemon.c:(.text+0x456): undefined reference to `sd_notifyf'
collect2: error: ld returned 1 exit status
Fix this by moving the systemd library dependencies from samba-util to
samba-util-core, the become_daemon.c base build target.

read_hex_bytes() is going to be used in lib/util/rfc1738.c.
parse_guid_string() is shifted for two reasons: Firstly, it is called
very often in some operations, sometimes constituting a few percent of
the CPU load, and it makes several calls to read_hex_bytes(). We want
the compiler to be able to inline those calls if it thinks that is
wise. Secondly, there are other places that could do with fast GUID
parsing.

triple-fork to avoid handling SIGCHLD in the parent.
This function is a workaround for the problem of using fork() in
library code. In that case the library should avoid setting a global
signal handler for SIGCHLD, because the application may wants to use its
own handler.
status_fd can be used to wait for the child to exit and get its exit
status.

Commit 670db6ac1d split tevent-util public
library to create tevent-unix-util public library for standalone ctdb
use. This created a public library dependency between samba and ctdb
for packaging.
Bundle tevent_unix.c in public library tevent-util as before. However,
to avoid the dependencies for packaging, standalone ctdb build will
build tevent-util as a private library with only tevent_unix.c
This simplifies any new subsystems (or libraries) which need tevent-util
and are linked in both samba and ctdb.

This removes quite a bit of code. All reasonable systems have /dev/urandom
these days. Linux, Solaris and the BSDs do. In case we find a system
without /dev/urandom, we will have to go hunting in other libraries.
The main reason for this is speed: On Ubuntu 14.04 doing direct reads from
/dev/urandom is 2-3 times faster than our md4 based code. On virtualized
FreeBSD 10 the difference is even larger.
My first approach was to use fopen/fread. It was even faster, but less
than twice as fast. So I thought we could save the additional complexity
when having to deal with throwing away buffers when forking and the
additional memory footprint per process.
With this simple generate_random_buffer it will be easier to adapt new
syscalls to get randomness.
