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.

It's a bit confusing to mix low-level and high-level libraries. We had
multiple libraries in one directory, and there were have circular
dependencies with other libraries outside that directory (in this case,
samba-hostconfig).

This passes down a struct loadparm_context to allow these
parameters to be checked. This may be s3 or s4 context, allowing the
#if _SAMBA_BUILD_ macro to go away safely.
Andrew Bartlett
This #if _SAMBA_BUILD == 3 is very unfortunate, as it means that in
the top level build, these options are not available for these
databases. However, having two different tdb_wrap lists is a worse
fate, so this will do for now.
Andrew Bartlett
This only sets up the random number generator callback these days, so
use a different database for that.
(All secrets data in Samba4 is in secrets.ldb)
Andrew Bartlett
thi ensures we are using the header corresponding to the version of
ldb we're linking against. Otherwise we could use the system ldb for
link and the in-tree one for include

A new event context is constructed by LDB when required for secrets.ldb
This will be essentially unused, as LDB on TDB will only trigger 'fake'
events, and blocks on transactions and lock operations anyway.
Andrew Bartlett
This code never really belonged in the credentials layer, and
is easier done with direct access to the ldb_message that is
in secrets.ldb.
Andrew Bartlett
this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

This also moves the calls to secrets_get_domain_sid back into
winbind_task_init(), so that we can terminate with a much more
detailed error message. (The previous message was simply
NT_STATUS_CANT_ACCESS_DOMAIN_INFO).
Andrew Bartlett
this with the provision, which sets up a very different database.
Removing this ensures we are consistant.

This patch changes a lot of the code in ldb_dn.c, and also
removes and add a number of manipulation functions around.
The aim is to avoid validating a dn if not necessary as the
validation code is necessarily slow. This is mainly to speed up
internal operations where input is not user generated and so we
can assume the DNs need no validation. The code is designed to
keep the data as a string if possible.
The code is not yet 100% perfect, but pass all the tests so far.
A memleak is certainly present, I'll work on that next.
Simo.
