apr history re-written

[smanders]

it appears apache/apr re-wrote their git history since externpro fork'ed at version 1.5.2

• https://github.com/apache/apr/compare/1.5.2...smanders:1.5.2
  • should match after updating fork history to match upstream history
• https://github.com/apache/apr/compare/1.5.2...smanders:x1.5.2
  • this is the diff between what was the 1.5.2 tag and what it is now
  • what was 1.5.2 tag is now renamed to x1.5.2
• https://github.com/apache/apr/compare/1.5.2...smanders:xp1.5.2
  • this diff should match the "patch"
• https://github.com/apache/apr/compare/1.5.2...smanders:xxp1.5.2
  • what was xp1.5.2 branch is now renamed to xxp1.5.2
  • this diff wasn't matching the "patch"
• https://github.com/smanders/apr/compare/x1.5.2...xxp1.5.2
  • the old tag and the old branch (which should match the "patch"

I cherry-pick'ed the commits from xxp1.5.2 to a new xp1.5.2 branch (starting from the new 1.5.2 tag)
