Changes with Apache 2.1.5

  [Remove entries to the current 2.0 section below, when backported]

  *) EBCDIC: Handle chunked input from client or, with proxy, origin
     server.  [Jeff Trawick]

  *) authn_provider_alias: Adds the configuration block tag
     <AuthnProviderAlias baseProvider Alias>
     Authentication directives contained within this block can be
     referenced as a new authProvider using the AuthBasicProvider or
     AuthDigestProvider directive.  These directives will be merged in to
     the per_dir configuration just before the base provider is called.
     [Brad Nicholes]

  *) ap_getword_conf: Fix backslashes at the end of configuration directives. 
     PR 34834. [Timo Viipuri <viipuri dlc.fi>]

  *) mod_dbd: New additions: mod_dbd.c, mod_dbd.h, mod_dbd.xml
     Provide module hooks for apr_dbd; optimise for httpd
     threaded and non-threaded arch [Nick Kew]

  *) ab: SSL support rewritten, improved, and enabled if SSL is enabled
     during the build; -f and -Z arguments added to specify SSL protocol
     options.  [Masaoki Kobayashi <masaoki techfirm.co.jp>]

  *) Support the suppress-error-charset setting, as with Apache 1.3.x.
     PR 31274.  [Jeff Trawick]

  *) Prevent hangs of child processes when writing to piped loggers at
     the time of graceful restart.  PR 26467.  [Jeff Trawick]
  
  *) mod_info: Show the Quick Handler [Paul Querna]

  *) mod_ldap: Add the directive LDAPVerifyServerCert to specify 
     whether to force verification of the server certificate when
     establishing an SSL connection to the LDAP server. 
     [Brad Nicholes]
     
  *) mod_proxy: Run mod_rewrite before mod_proxy in the translate_name
     hook. [Paul Querna]

  *) Add AP_INIT_TAKE_ARGV for configuration commands. (minor MMN bump) 
     [Paul Querna]

  *) worker and event mpms: don't take down the whole server for a transient
     thread creation failure.  PR 34514 [Greg Ames]

  *) ap_get_local_host() rewritten for APR. [Jim Jagielski]

     applications that send the Vary Header themselves, and also apply 
     mod_defalte as an output filter. [Paul Querna]

     can result in a major performance improvement when the files are
     large.

     for UseCanonicalName to Off.
     [Joshua Slive]

     UserDir directive is present in the config file.
     [Joshua Slive]

  *) Massively simplify the distributed httpd.conf by removing
     many features and many directives that are at their default
     setting.  Add a selection of example config excerpts for adding
     extra features in the conf/extra/ directory.  Install the
     distributed config and the extra config examples in the
     conf/original/ directory during make install.
     [Joshua Slive, Justin Erenkrantz]

  *) NetWare: Reposition mod_asis, mod_actions, mod_cgi, mod_imagemap,
     mod_userdir and mod_autoindex as shared modules rather than 
     built-in modules within the NetWare build.
     [Brad Nicholes]

  *) Rename mod_imap to mod_imagemap.
     [Paul Querna]
