Rename list_subid_ranges to getsubids to provide a system binary to
check the sub*ids of a user. The intention is to provide this binary
with any distribution that includes the subid feature, so that system
administrators can check the subid ranges of a given user.
Finally, add a man page to explain the behaviour of getsubids.

In some circumstances I want the default behaviour of useradd to
not add user entries to the lastlog and faillog databases. Allowing
this options behaviour to be controlled by the config file
/etc/default/useradd.
xml2po is deprecated. We've previously replaced xml2po with
itstool in man/generate_translations.mak, but there was still
an instance of it that only is exercised for 'make dist'.
Update that one. Now 'make dist' succeeds on a ubuntu focal
or newer host where xml2po is not available.

Following the discussion https://github.com/shadow-maint/shadow/pull/345
I have changed the documentation to clarify the behaviour of subid
delegation when any subid source except files is configured.
Clarify that the subid delegation can only come from one source.
Moreover, add an example of what might happen if the subid source is NSS
and useradd is executed.

Include the new HMAC_CRYPTO_ALGO key that is needed by pam_timestamp to
select the algorithm that is going to be used to calculate the message
authentication code.
pam_timestamp is currently using an embedded algorithm to calculate the
HMAC message, but the idea is to improve this behaviour by relying on
openssl's implementation. On top of that, the ability to change the
algorithm with a simple configuration change allows to simplify the
process of removing unsecure algorithms.

man/usermod.8.xml: specify what happens when the current home directory
doesn't exist if using -d and -m options. Moreover, specify what happens
when the group ownership is changed and the uid's don't match in -u and
-g options.
man/shadow.5.xml: indicate the exact time and timezone for the dates.
Moreover, clarify that when the password expires the user won't be able
to login.
man/chage.1.xml: Indicate that -d option with a value of 0 forces the
user to change his password. Besides, set an example on how to use -E
option. Finally, add a general note to clarify that chage only takes
charge of local users and another note to indicate that it doesn't check
inconsistencies between shadow and passwd files.
According to crypt(5), MD5 and DES should not be used for new
hashes. Also the default number of SHA rounds chosen by libc is orders
of magnitude too low for modern hardware. Let's warn the users about
weak choices.

Explanation: clarify the useradd -d parameter as it does create directory HOME_DIR if it doesn't exit.
