After packaging drops LegacyVersion (see pypa/packaging#407), packaging.version.parse() will no longer guarantee to be able to parse Git versions, so we need to invent our own parser. Since we really only care about the major and minor segments, the logic is pretty simple.

I only searched the code base for LegacyVersion, LegacySpecifier, version.parse, and parse_version. There are a couple of LegacyVersion references that cannot be removed yet, but we can do them quickly enough. Hopefully I did not miss anything.

Bump pip from 21.1.3 to 21.2.1 (PR #3139)
7c85232 
Bumps [pip](https://github.com/pypa/pip) from 21.1.3 to 21.2.1.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a href="https://github.com/pypa/pip/blob/main/NEWS.rst">pip's changelog</a>.</em></p>
<blockquote>
<h1>21.2.1 (2021-07-25)</h1>
<h2>Process</h2>
<ul>
<li>The source distribution re-installation feature removal has been delayed to 21.3.</li>
</ul>
<h1>21.2 (2021-07-24)</h1>
<h2>Process</h2>
<ul>
<li><code>pip freeze</code>, <code>pip list</code>, and <code>pip show</code> no longer normalize underscore
(<code>_</code>) in distribution names to dash (<code>-</code>). This is a side effect of the
migration to <code>importlib.metadata</code>, since the underscore-dash normalization
behavior is non-standard and specific to setuptools. This should not affect
other parts of pip (for example, when feeding the <code>pip freeze</code> result back
into <code>pip install</code>) since pip internally performs standard PEP 503
normalization independently to setuptools.</li>
</ul>
<h2>Deprecations and Removals</h2>
<ul>
<li>Git version parsing is now done with regular expression to prepare for the
pending upstream removal of non-PEP-440 version parsing logic. (<code>[#10117](pypa/pip#10117) &lt;https://github.com/pypa/pip/issues/10117&gt;</code>_)</li>
<li>Re-enable the &quot;Value for ... does not match&quot; location warnings to field a new
round of feedback for the <code>distutils</code>-<code>sysconfig</code> transition. (<code>[#10151](pypa/pip#10151) &lt;https://github.com/pypa/pip/issues/10151&gt;</code>_)</li>
<li>Remove deprecated <code>--find-links</code> option in <code>pip freeze</code> (<code>[#9069](pypa/pip#9069) &lt;https://github.com/pypa/pip/issues/9069&gt;</code>_)</li>
</ul>
<h2>Features</h2>
<ul>
<li>
<p>New resolver: Loosen URL comparison logic when checking for direct URL reference
equivalency. The logic includes the following notable characteristics:</p>
<ul>
<li>The authentication part of the URL is explicitly ignored.</li>
<li>Most of the fragment part, including <code>egg=</code>, is explicitly ignored. Only
<code>subdirectory=</code> and hash values (e.g. <code>sha256=</code>) are kept.</li>
<li>The query part of the URL is parsed to allow ordering differences. (<code>[#10002](pypa/pip#10002) &lt;https://github.com/pypa/pip/issues/10002&gt;</code>_)</li>
</ul>
</li>
<li>
<p>Support TOML v1.0.0 syntax in <code>pyproject.toml</code>. (<code>[#10034](pypa/pip#10034) &lt;https://github.com/pypa/pip/issues/10034&gt;</code>_)</p>
</li>
<li>
<p>Added a warning message for errors caused due to Long Paths being disabled on Windows. (<code>[#10045](pypa/pip#10045) &lt;https://github.com/pypa/pip/issues/10045&gt;</code>_)</p>
</li>
<li>
<p>Change the encoding of log file from default text encoding to UTF-8. (<code>[#10071](pypa/pip#10071) &lt;https://github.com/pypa/pip/issues/10071&gt;</code>_)</p>
</li>
<li>
<p>Log the resolved commit SHA when installing a package from a Git repository. (<code>[#10149](pypa/pip#10149) &lt;https://github.com/pypa/pip/issues/10149&gt;</code>_)</p>

Bump pip's src from 20.1.1 to 21.2.4
f446856 
WARNING: fetchcode's vcs will not work on this commit.
This is result of separating pip's code from changes made in scope of
this repository.

This should make it easier to track potentially replicated issues from
pip when taking their vcs pkg.

It also made cleaning up easier, due to some maintenance activities done
in pip:
- dropping Python 2 & 3.5 support
  pypa/pip#9189
- modernized code after above - partially done, tracked in:
  pypa/pip#8802
- added py3.9 support
- updated vendored libraries (e.g. fixing CVE-2021-28363)
  multiple PRs

pip._internal.vcs (and related code) changes:
- Fetch resources that are missing locally:
  pypa/pip#8817
- Improve SVN version parser (Windows)
  pypa/pip#8665
- Always close stderr after subprocess completion:
  pypa/pip#9156
- Remove vcs export feature:
  pypa/pip#9713
- Remove support for git+ssh@ scheme in favour of git+ssh://
  pypa/pip#9436
- Security fix in git tags parsing (CVE-2021-3572):
  pypa/pip#9827
- Reimplement Git version parsing:
  pypa/pip#10117

In next commits, most of pip's internals will be removed from fetchcode,
leaving only vcs module with supporting code (like utils functions,
tests (which will be added & submitted with this change))

This will allow for changes such as ability to add return codes
(probably via futures) from long running downloads and other features.

Switching to having own vcs module might also be a good call due to
pip._internal.vcs close integration with pip's cli in vcs module (some
pip code has been commented out in commit mentioned below)

While generally copy-pasting code without history is bad idea, this
commit follows precedence set in this repo by:
8046215
with exception that all changes to pip's code will be submitted as separate
commits.

It has been agreed with @pombredanne & @TG1999 that history from pip
will be rebased on fetchcode by @pombredanne (thanks!). It will be done
only for the files that are of concern for fetchcode to limit noise in
git history.

I'm leaving this commit without SoB intentionally, as this is not my
work, but that of the many pip's authors:
