82856923bf auth-filters: use crypt() in simple-authentication
There's no use in giving a silly example to folks who will just copy it,
so instead try to do something slightly better.

c3b5b5f648 auth-filters: do not use HMAC-SHA1
Though SHA1 is broken, HMAC-SHA1 is still fine. But let's not push our
luck; SHA256 is more sensible anyway.

Otherwise we get the classic Python UTF-8 errors, and the text is all

d6e9200cc3 auth: add basic authentication filter framework
This leverages the new lua support. See
filters/simple-authentication.lua for explaination of how this works.
There is also additional documentation in cgitrc.5.txt.

Though this is a cookie-based approach, cgit's caching mechanism is
preserved for authenticated pages.

Very plugable and extendable depending on user needs.

The sample script uses an HMAC-SHA1 based cookie to store the
currently logged in user, with an expiration date.

ceffeb5d52 filters: Improved syntax-highlighting.py
- Switched back to python2 according to a problem in pygments with python3.
  With the next release of pygments this problem should be fixed.
  Issue see here:
  https://bitbucket.org/birkenfeld/pygments-main/issue/901/problems-with-python3
- Just read the stdin, decode it to utf-8 and ignore unknown signs. This ensures
  that even destroyed files do not cause any errors in the filter.
- Improved language guessing:
  -> At first use guess_lexer_for_filename for a better detection of the used
     programming languages (even mixed cases will be detected, e.g. php + html).
  -> If nothing was found look if there is a shebang and use guess_lexer.
  -> As default/fallback choose TextLexer.

7ea35f9f8e syntax-highlighting.sh: Fix command injection.
By not quoting the argument, an attacker with the ability to add files
to the repository could pass arbitrary arguments to the highlight
command, in particular, the --plug-in argument which can lead to
arbitrary command execution.

This patch adds simple argument quoting.

d14faf4424 syntax-highlight: when the file has no extension, assume text
There are 2 situations:
1- empty extension: assuming text is better than highlight
   producing no output because of a missing argument.
2- no extension at all: assuming text is better than setting
   the extension to the filename, which is what now happens.
