Add Support for Environment Variables and HTTP Authentication

Added

• Configuration file tower: Degasolv looks for config files in pre-defined
  locations on the file system if they exist, see
  "Default Configuration Files" in the docs.

• Environment variable support: environment variables are consulted first,
  but are merged into the option map AFTER config file material and BEFORE
  any given command line options, see
  "Environment Variables" and "How Options are Gathered" in the docs.

• Added support for HTTP/HTTPS authentication using basic, oauth2 token
  and header methods, see "A Note on Specifying Files" in the docs.

Changed

• Removed deprecated, unused function degasolv.util.assoc-conj

Fixed

• Option packs are expanded at the level upon which they are defined, then the
  options are merged together. This seemed like a bug that needed fixing.
  See "Option Packs" in the docs for more information.

Add Support for Minimum Version Selection

Added

• Added "version suggestion", a performance enhancement allowing for minimum
  version selection

• Added the :index-sort-order option to generate-repo-index,
  allowing users to specify ascending or descending. Previously
  only descending was supported. With this new option,
  users will be able to use Degasolv in a minimum version selection
  configuration.

• If the reason for failure in the resolve-dependencies function
  is :present-package-conflict, add a key :package-present-by with
  value as either :found meaning the package was in conflict with a package
  found during resolution, or with value as :given meaning the package
  was in conflict with a package given via the parameter present-packages.

Changed

• Removed the deprecated functions ->requirement, ->package, and
  ->version-predicate from usage in the code base.

• Removed dbg2 macro in favor of keeping dbg

Fixed

• Standardized capitalization of the word "Degasolv" to be title case for
  consistency in the documentation unless it is in a code snippet.

• Fix #16

• Fix spec for package id's. This should have the effect of enforcing that
  names should not have >, <, !, =, ,, ;, or |
  characters in them. This simply has the effect of changing the error message,
  as this was never allowed but handled poorly.

Update Various Argument Defaults

Added

• Documentation saying what return codes are given and what they mean.

• For #15, added ability to specify output format for display-config.

• Added 3rd Party Licenses document

Changed

• In the docs, java -jar degasolv-<version>-standalone.jar changed to
  degasolv with added note for clarity

• For #13, return code for resolve-locations changed to 3 when dependency
  resolutions occur to distinguish them from normal "you got the argument
  string wrong" errors

• Default --{enable|disable}-error-format set to enabled for
  resolve-locations and
  query-repo.

• Default for --list-strat option for resolve-locations set to lazy, a
  much saner default.

• Option pack v1 added to help administrators
  keep compatibility with version 1 of degasolv if required.

• Default for the --version-comparison option when --package-system is
  degasolv set to semver for generate-repo-index, resolve-locations and
  query-repo.

• Removed less-than-useful warning about absent config files.

Fixed

• Fixed #14, "Degasolv pulls in X"

• Fixed bug where display-config didn't allow the user
  to specify valid options for other things, now it does

• Fixed bug where index.dsrepo didn't generate anything except
  an empty map inside the file. This was completely broken.

• Fixed #6, "If one config file fails to load, the rest do as well"

• Fixed #9, "Heading for 'Specifying Subproc Executable' is wrong in docs"

• Fixed #10, "How do you specify requirements of a package (deps) in the output
  of a subproc to degasolv?"

Add list-strat and subproc-exe

Added

• Added the --{enable|disable}-error-format options to
  resolve-location and query-repo.

• Added the --package-system subproc option, together with its
  --subproc-exe and --subproc-output-format options.

• Added the --json-config global option allowing users
  to use JSON config files

• Added the --list-strat option to resolve-locations, allowing users to have their dependencies listed in a sane order.

Fixed

• JSON/EDN output for query-repo erroneously listed the subcommand as
  resolve-locations. Fixed.

Add the ability to specify additional metadata; output it in queries

• Added the --meta option to generate-card
• Added metadata a la --meta to the apt package system
• Added the edn output format option for the resolve-locations subcommand
• Added the --output-format option to the query-repo command

Add `--output-format` option to resolve-locations

Added the --output-format option to the resolve-locations subcommand. This allows the operator to get information about the run in JSON form instead of plain text.

Added pessimistically greater

Added

• Added the pessimistic greater-than comparison operator ><.

Fixed

• Removed validation from the config file option, allowing it to be a URL or
  anything else.

• If no arguments are given, the help screen is now printed instead of a wierd
  error.

Add some polish

Added

• Distribution is now done via RPM and Debian package as well as JAR file
• Added the --version-comparison option resolve-locations and query-repo,
  allowing the user to specify which version comparison algorithm is used.
• Added the --search-strat option to resolve-locations`, allowing users to select breadth first
  search or depth first search during resolution
• Added the "matches" operator (<>REGEX) which
  matches a version against a regex
• Added the "in-range" operator (=>V) which
  matches a version against a certain range of indexes
• Added the ability to specify --present-package multiple times using the
  same package name, but different versions. This is useful for when the
  :conflict-strat is set to inclusive.
• Added tests testing to make sure that unsuccessful runs generate the proper
  error messages.

Changed

• Reorganized the unit tests.
• Alphabetized the options for generate-card.
• Alphabetized the options for generate-repo-index.

Fixed

• Fixed bug wherein if the conflict strategy is set to :inclusive
  and a package satisfying a requirement is already found or present,
  it is used instead of finding a new one.
• Fixed CLI of display-config so that
  it actually works as advertised, LOLZ
• Fixed the CLI output of --help so that default values
  of options are shown again :)
• Refreshed the CLI output of --help for all the subcommands
  as posted in the docs

Add ``--option-pack``, fix bugs

Added

• Added --option-pack, the ability to specify multiple options

Fixed

• Fixed how default options work, they no longer override stuff
  found in the config file (ouch)
• Fixed output of printed warning when configuration file is not used

Improve ``display-config`` and docs

Added

• Formatted docs better on the front page for PDF purposes
• Add ability to use any (long) option on the command line in display-config

Improved

• Memoized core Degasolv package system repository function (should speed the resolver up a bit)
• Changed apt repo function from filtering a list to lookup in a map, increasing its speed
