the secure key repository provided by the keystore implementation
introduced in the previous commit.

Add a keystore implementation that stores secure AES keys in a
key repository, located in a directory, e.g. '/etc/zkey/repository'.
The keystore allows you to generate, validate, re-encipher, modify,
list, delete, etc secure keys.

To reduce the size of the zkey.c source file, all routines that
deal with secure keys are moved to a new source file pkey.c.

Comma separated strings are used in property values to store
multiple values in one property. These helper functions allow to
work with such comma separated strings.

The integrity support for the properties file routines use
SHA-256 to build a hash of the keys and values of a property file.
The codes uses the EVP_DigestInit_ex, EVP_DigestUpdate, and
EVP_DigestFinal from the libcrypto library (OpenSSL).

In preparation for a new feature, introduce property file
handling routines. A property file stores key value pairs
in a text file. Optionally a hash of all keys and values
contained in the properties file can be generated to
ensure integrity of the properties file and to detect
manual modifications.

Abbreviated commands are not recognized and zkey issues an invalid
command error.
In is_command(), the abbreviated command string is copied into the
command_str variable. Because this variable is not initialized and,
thus, might contain arbitrary data, a NUL-terminated is not guaranteed.
The following string comparison is very likely to fail. Correct this
problem by comparing up to the length of the command string only.

Few options are displayed with their argument concatenated. This
is due to the nature of the .BR roff macro. Ensure to separate them
with a blank (using "\~" which is an unbreakable space that stretches
like a normal inter-word space when a line is adjusted).

When validating an XTS key, the 2 key parts are validated separately.
This can happen on different crypto cards, when more than one crypto
card is available to the system. Each key part can be validated on
a different card, however, the 2 cards need to have the same master
key, thus the master key validation pattern contained in the 2 key
parts are checked.

The LDFLAGS content is added before the object files causing unresolved
symbol dereferences during the build. This actually happens so far on
Debian/Ubuntu instances.
Hence, use LDLIBS instead.
