#184022 bx chx and merlinofchaos with documentation improvements from me: %index and %map menu path placeholders for Views module to be able to use the new menu system

- Patch #172582 by webchick, gabor, eaton, kentbyte, tresler, alpritt et al: improved the OpenID help texts.

#55277 by catch and JirkaRybka: when flat comment view is used, order comments by cid (ie. original submission order) instead of timestamp (ie. last editing time order) to avoid comments jumping around when being edited

#183690 by Wim Leers: (developer improvement) abstract path matching to drupal_match_path() from block listing, so this gets reusable when path based matching is required

#181328: pass on whole form to #process functions to enable advanced form handling (such as required by some CCK widgets)

 - always prune the whole cache as string additions affect all languages
 - rebuild the language caches as needed, distributing this load among page requests

 - book outline form reordering in real-time
 - better context sensitive book parent editing

#183390 by hunmonk: forms should use form_state['redirect'] for redirection, not drupal_goto() - fix this in comment_admin_overview_submit()

#169079 by yched: improve consistency of menu API and batch API by allowing batch definition in non .module files, which opens the possibility of better performing batches (which are likely to reside in .admin.inc files generally)
 - apply this change in locale.module
 - improve batch API code documentation

Four watchdog() calls which still used t(), identified by myself after implementing extraction code for Drupal 6 at #182765

#72487 by chx, pwolanin and moshe weitzman: let node_access() work on arbitrary users, so independent user access checks can be done in a request

#175117 by kbahey: developer improvement: include caller function name and user name in SQL queries for the query log when debug mode is turned on, so debugging gets easier

#172588 follow up note by Freso, patch by me: concatenation coding style fixes at end of lines in color module help

#180897 by sun and dvessel: fix various XHTML validity issues in Drupal by closing unclosed tags, avoiding empty table containers, and so on

#182410 by greggles: HTTP Basic authentication username and password was parsed in drupal_http_request() but then not used in the request

#182310 by chx: remove #DANGEROUS_SKIP_CHECK, as with the AHAH functionality now we have safer methods to add things in the cached form for validation, so we don't need this security hole possibility kept anymore.

#178768 follow up patch by myself: now that we know Drupal module is moved to site_network, we can document is in the changelog

#181741 by quicksketch: fix AHAH throbber/progress bar issues and generalize progress display configuration to allow module developers to choose from the throbber and progress bar

#181758 by webernet: move cache_block creation to update_fix_d6_requirements() to avoid warnings about the nonexistent table through the update process

#180588 by merlinofchaos: run tabs through theme('menu_item_link') compared to just l() directly, so they can be properly themed

#181564 by Crell: add first and last CSS classes to menu tree lists and themed item lists for themers to use
