Fixes the following security issues:
CVE-2019-14232: Denial-of-service possibility in django.utils.text.Truncator
If django.utils.text.Truncator's chars() and words() methods were passed the
html=True argument, they were extremely slow to evaluate certain inputs due
to a catastrophic backtracking vulnerability in a regular expression. The
chars() and words() methods are used to implement the truncatechars_html and
truncatewords_html template filters, which were thus vulnerable.
The regular expressions used by Truncator have been simplified in order to
avoid potential backtracking issues. As a consequence, trailing punctuation
may now at times be included in the truncated output.
CVE-2019-14233: Denial-of-service possibility in strip_tags()
Due to the behavior of the underlying HTMLParser,
django.utils.html.strip_tags() would be extremely slow to evaluate certain
inputs containing large sequences of nested incomplete HTML entities. The
strip_tags() method is used to implement the corresponding striptags
template filter, which was thus also vulnerable.
strip_tags() now avoids recursive calls to HTMLParser when progress removing
tags, but necessarily incomplete HTML entities, stops being made.
Remember that absolutely NO guarantee is provided about the results of
strip_tags() being HTML safe. So NEVER mark safe the result of a
strip_tags() call without escaping it first, for example with
django.utils.html.escape().
CVE-2019-14234: SQL injection possibility in key and index lookups for
JSONField/HStoreField
Key and index lookups for django.contrib.postgres.fields.JSONField and key
lookups for django.contrib.postgres.fields.HStoreField were subject to SQL
injection, using a suitably crafted dictionary, with dictionary expansion,
as the **kwargs passed to QuerySet.filter().
CVE-2019-14235: Potential memory exhaustion in
django.utils.encoding.uri_to_iri()
If passed certain inputs, django.utils.encoding.uri_to_iri could lead to
significant memory usage due to excessive recursion when re-percent-encoding
invalid UTF-8 octet sequences.
uri_to_iri() now avoids recursion when re-percent-encoding invalid UTF-8
octet sequences.

Fixes the following security issues:
CVE-2019-12308: AdminURLFieldWidget XSS¶
The clickable "Current URL" link generated by AdminURLFieldWidget displayed
the provided value without validating it as a safe URL. Thus, an
unvalidated value stored in the database, or a value provided as a URL query
parameter payload, could result in an clickable JavaScript link.
AdminURLFieldWidget now validates the provided value using URLValidator
before displaying the clickable link. You may customize the validator by
passing a validator_class kwarg to AdminURLFieldWidget.__init__(), e.g.
when using formfield_overrides.
Patched bundled jQuery for CVE-2019-11358: Prototype pollution¶
jQuery before 3.4.0, mishandles jQuery.extend(true, {}, ...) because of
Object.prototype pollution. If an unsanitized source object contained an
enumerable __proto__ property, it could extend the native Object.prototype.
The bundled version of jQuery used by the Django admin has been patched to
allow for the select2 library’s use of jQuery.extend().

Fixes the following security issues:
CVE-2019-6975: Memory exhaustion in django.utils.numberformat.format()
If django.utils.numberformat.format() – used by contrib.admin as well as the
the floatformat, filesizeformat, and intcomma templates filters – received a
Decimal with a large number of digits or a large exponent, it could lead to
significant memory usage due to a call to '{:f}'.format().
To avoid this, decimals with more than 200 digits are now formatted using
scientific notation.

This commit fixes the warnings reported by check-package on the help
text of all package Config.in files, related to the formatting of the
help text: should start with a tab, then 2 spaces, then at most 62
characters.
The vast majority of warnings fixed were caused by too long lines. A
few warnings were related to spaces being used instead of a tab to
indent the help text.
