[PATCH 00/13] Fixes for problems detected by Sparse

[John Keeping]

Sparse[0] detects several potential problems in CGit, which are all
fixed by this set of patches.  Most of these are style issues that are
correct either way (using integer zero as a NULL pointer), but I think
there is value in keeping the build clean of Sparse warnings.

John Keeping (13):
  Makefile: add a target to run CGit through sparse
  Avoid non-ANSI function declarations
  Avoid signed bitfields
  scan-tree: make some variables 'static'
  shared: make some variables 'static'
  ui-log: make some variables 'static'
  ui-repolist: make sortcolumn definitions 'static const'
  ui-shared: make cgit_doctype 'static'
  ui-stats: make cgit_period definitions 'static const'
  ui-shared: avoid initializing static variable to zero
  ui-shared: don't use an integer as a NULL pointer
  cache: don't use an integer as a NULL pointer
  html: avoid using a plain integer as a NULL pointer
