The DTLSv1_listen function is intended to be stateless and processes

Fix probable_prime over large shift
In the probable_prime() function we behave slightly different if the number
of bits we are interested in is <= BN_BITS2 (the num of bits in a BN_ULONG).
As part of the calculation we work out a size_limit as follows:
size_limit = (((BN_ULONG)1) << bits) - BN_get_word(rnd) - 1;
There is a problem though if bits == BN_BITS2. Shifting by that much causes
undefined behaviour. I did some tests. On my system BN_BITS2 == 64. So I
set bits to 64 and calculated the result of:
(((BN_ULONG)1) << bits)
I was expecting to get the result 0. I actually got 1! Strangely this...
(((BN_ULONG)0) << BN_BITS2)
...does equal 0! This means that, on my system at least, size_limit will be
off by 1 when bits == BN_BITS2.
This commit fixes the behaviour so that we always get consistent results.

Fix unintended sign extension
The function CRYPTO_128_unwrap_pad uses an 8 byte AIV (Alternative Initial
Value). The least significant 4 bytes of this is placed into the local
variable |ptext_len|. This is done as follows:
ptext_len = (aiv[4] << 24) | (aiv[5] << 16) | (aiv[6] << 8) | aiv[7];
aiv[4] is an unsigned char, but (aiv[4] << 24) is promoted to a *signed*
int - therefore we could end up shifting into the sign bit and end up with
a negative value. |ptext_len| is a size_t (typically 64-bits). If the
result of the shifts is negative then the upper bits of |ptext_len| will
all be 1.

Rethink templates.
Because base templates express inheritance of values, the attribute is
renamed to 'inherit_from', and texts about this talk about 'inheritance(s)'
rather than base templates.
As they were previously implemented, base templates that were listed
together would override one another, the first one acting as defaults for
the next and so on.
However, it was pointed out that a strength of inheritance would be to
base configurations on several templates - for example one for CPU, one
for operating system and one for compiler - and that requires a different
way of combining those templates. With this change, inherited values
from several inheritances are concatenated by default (keep on reading).
Also, in-string templates with the double-curly syntax are removed,
replaced with the possibility to have a configuration value be a coderef
(i.e. a 'sub { /* your code goes here */ }') that gets the list of values
from all inheritances as the list @_. The result of executing such a
coderef on a list of values is assumed to become a string. ANY OTHER
FORM OF VALUE WILL CURRENTLY BREAK.
As a matter of fact, an attribute in the current config with no value is
assumed to have this coderef as value:
sub { join(' ', @_) }

Add base template processing.
Base templates are templates that are used to inherit from. They can
loosely be compared with parent class inheritance in object orientation.
They can be used for the same purpose as the variables with multi-field
strings are used in old-style string configurations.
Base templates are declared with the base_templates configuration
attribute, like so:
"example_target" => {
base_templates => [ "x86_asm", ... ]
...
}
Note: The value of base_templates MUST be an array reference (an array
enclosed in square brackets).
Any configuration target can be used as a base template by another. It
is also possible to have a target that's a pure template and not meant to
be used directly as a configuration target. Such a target is marked with
the template configuration attribute, like so:
"example_template" => {
template => 1,
cc => "mycc",
...
},

Rewrite Configure to handle the target values as hash tables.
The reasoning is that configuration strings are hard to read and error
prone, and that a better way would be for them to be key => value hashes.
Configure is made to be able to handle target configuration values as a
string as well as a hash. It also does the best it can to combine a
"debug-foo" target with a "foo" target, given that they are similar
except for the cflags and lflags values. The latter are spliced into
options that are common for "debug-foo" and "foo", options that exist
only with "debug-foo" and options that exist only with "foo", and make
them into combinable attributes that holds common cflags, extra cflags
for debuggin and extra cflags for non-debugging configurations.
The next step is to make it possible to have template configurations.

Prevent handshake with unseeded PRNG
Fix security issue where under certain conditions a client can complete a
handshake with an unseeded PRNG. The conditions are:
- Client is on a platform where the PRNG has not been seeded, and the
user has not seeded manually
- A protocol specific client method version has been used (i.e. not
SSL_client_methodv23)
- A ciphersuite is used that does not require additional random data
from the PRNG beyond the initial ClientHello client random
(e.g. PSK-RC4-SHA)
If the handshake succeeds then the client random that has been used will
have been generated from a PRNG with insufficient entropy and therefore
the output may be predictable.
For example using the following command with an unseeded openssl will
succeed on an unpatched platform:
openssl s_client -psk
1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA
