This allows for libloc to be better integrated into third-party
software.

If we would add extra flags, we would be able to extend it in libloc
without touching any third-party software.

This one apparently went down the drain between these two patches:
- https://patchwork.ipfire.org/project/location/patch/20210522125758.28770-1-peter.mueller@ipfire.org/
- https://patchwork.ipfire.org/project/location/patch/aefd1904-4b38-f5cf-ab1d-9d69636cf914@ipfire.org/

Due to other safeguards, the current damage in production is limited to:

A decent amount of autnum objects - especially, but not exclusively in
the APNIC sector - does not contain a link to an organisation handle.

In such cases, this patch is going to use the first description line of
the atunum object in question (if available) as a string for its name.
The overwhelming majority of affected ASNs contains a valuable
information there, so this is almost as good as having an organisation
handle linked to it.

- Update for maintainer name and email address, as to reflect who
  actually prepared this release of the package. It was not me,
  but I was selected due to having the first commit on the package.

  To mitigate against this, when running the `debchange --release`
  (`dch -r`) command, environment variables DEBFULLNAME and DEBEMAIL
  should be configured properly for the current user.

- Removal of NMU comment on my name, as I am not really doing a
  non-maintainer upload. I would say the 'NMU' message is fairly
  useless on this repository, as it is self-maintained here.

This commit further builds on historical changelog modifications,
to properly attribute all authors of the commits.

An additional d/genchangelog.sh script has been added. This allows
generation of changelog entries, internally using `debchange` (`dch`).
The script accepts an argument, which is the commit range to generate
entries for. Each commit's subject line (first line of body) is used,
along with author name and email. This information is added to the
changelog. Automatic detection (via `debchange` built-in functionality)
is used to determine whether these entries should be added to an
existing version number. If there is no UNRELEASED version, then a new
version is automatically tagged.

The new version tag will usually need to be modified, for example,
replacing an automatically generated 0.9.6-2 with 0.9.7-1.

The final release change (s/UNRELEASED/unstable/) needs to be done
manually as well, when the Git tag is actually being tagged.
`dch -r` can be useful for this particular purpose.

location-import.in: optimise regular expression for filtering ASN allocations to other RIRs when parsing ARIN AS names file

There are muiltiple standards of listing symbols throughout the Linux
ecosystem. For `dpkg`, a d/package.symbols file tracks symbols, and in
which version they were added in. This is then used to allow dependency
checks/resolution.

See man:dpkg-gensymbols(1) for details about the generation,
and man:dpkg-shlibdeps(1) for how the symbols file ends up being used.

This commit adds a d/libloc1.symbols file, containing the current state
of the symbols. There is now also a d/gensymbols.sh script, which
generates this symbols file. The script tries to determine what Git
tags need to be checked for changes in symbols, by looking at current
maximum version referenced in symbols file.

After checking tags, the current revision is also processed, to allow
building symbols file for a yet unreleased version (prior to tagging it).
This is to allow symbols changes to be included in a tag.

Do keep in mind, that for the workflow above, when running the script,
the d/changelog file should contain information about what version the
current revision will be released at (potentially tagged as UNRELEASED
in the d/changelog file). Otherwise, if there is no version tagged,
the `dpkg-gensymbols` tool will use the old version information,
in turn incorrectly attributing new symbols to an old version.

When an invalid country code is entered, loc_country_new returns an
error which is interpreted as a match to the list since we check for a
non-zero return code.

Amazon publishes information regarding some of their IP networks
primarily used for AWS cloud services in a machine-readable format. To
improve libloc lookup results for these, we have little choice other
than importing and parsing them.

Unfortunately, there seems to be no machine-readable list of the
locations of their data centers or availability zones available. If
there _is_ any, please let the author know.

The second version of this patch adds a meaningful description for the
"source" column in the overrides tables, to make introduced changes
less intransparent.

ARIN and LACNIC, unfortunately, do not seem to publish data containing
human readable AS names. For the former, we at least have a list of
tecnical names, which this patch fetches and inserts into the autnums
table.

While some of them do not seem to be suitable for human consumption (i.
e. being very cryptic), providing these data might be helpful
neverthelesss.

This patch implements an additional flag intended for networks and
Autonomous Systems being considered hostile. While libloc does not and
should not be an opinionated database, reality shows it is being used
this way.

Hereby, we assign "XD" (drop) as a custom country code for networks
being flagged this way. According to ISO, "XA" to "XZ" are reserved for
"user-assgined codes" (https://www.iso.org/glossary-for-iso-3166.html),
so this is a safe thing to do.

This patch does not interfere with "A1" to "A3", which we currently
assign outside standardised country code ranges for historical reasons.

Neither does it specify any policy or source for tagging networks with a
"drop" flag. Doing so is beyond the scope of this - technical -
approach.

To avoid confusions with the SQL "DROP" command, "is_drop" will be used
as a column name for database operations.

Thanks to Michael for his remarks and ideas during the run-up.

This allows us to trace back concrete changes or anomalies to their RIR
source, without having to parse everything again. Further, it enables
adding 3rd party sources such as IP feeds from Amazon, without loosing
track of the changes introduced by them.
