Peter Wemm af80ed6add Update from svn-1.8.14 to 1.9.2. 
Formal release notes are available:
  https://subversion.apache.org/docs/release-notes/1.9.html

Of particular note, the client checkout format has *not* changed so
upgrades should *not* be required.

When reading a repository (file:// or running as a local server), an
improved fsfs version 7 is available with significant performance
improvements.  An optional upgrade is possible to use the new features.
Without the upgrade, this is fully read/write compatible with the
version 6 fsfs as in svn-1.8.

Relnotes:	yes

*
* Set @a *allowed to TRUE to indicate that the @a required access on
* @a path in @a root is authorized, or set it to FALSE to indicate
* unauthorized (presumable according to state stored in @a baton).
*
* If @a path is NULL, the callback should perform a global authz
* lookup for the @a required access. That is, the lookup should
* check if the @a required access is granted for at least one path of
* the repository, and set @a *allowed to TRUE if so. @a root may
* also be NULL if @a path is NULL.
*
* This callback is very similar to svn_repos_authz_func_t, with the
* exception of the addition of the @a required parameter.
* This is due to historical reasons: when authz was first implemented
* for svn_repos_dir_delta2(), it seemed there would need only checks
* for read and write operations, hence the svn_repos_authz_func_t
* callback prototype and usage scenario. But it was then realized
* that lookups due to copying needed to be recursive, and that
* brute-force recursive lookups didn't square with the O(1)
* performances a copy operation should have.
*
* So a special way to ask for a recursive lookup was introduced. The
* commit editor needs this capability to retain acceptable
* performance. Instead of revving the existing callback, causing
* unnecessary revving of functions that don't actually need the
* extended functionality, this second, more complete callback was
* introduced, for use by the commit editor.
*
* Some day, it would be nice to reunite these two callbacks and do
* the necessary revving anyway, but for the time being, this dual
* callback mechanism will do.

/* Reporting the state of a working copy, for updates. */
/**
* Construct and return a @a report_baton that will be passed to the
* other functions in this section to describe the state of a pre-existing
* tree (typically, a working copy). When the report is finished,
* @a editor/@a edit_baton will be driven in such a way as to transform the
* existing tree to @a revnum and, if @a tgt_path is non-NULL, switch the
* reported hierarchy to @a tgt_path.
*
* @a fs_base is the absolute path of the node in the filesystem at which
* the comparison should be rooted. @a target is a single path component,
* used to limit the scope of the report to a single entry of @a fs_base,
* or "" if all of @a fs_base itself is the main subject of the report.
*
* @a tgt_path and @a revnum is the fs path/revision pair that is the
* "target" of the delta. @a tgt_path should be provided only when
* the source and target paths of the report differ. That is, @a tgt_path
* should *only* be specified when specifying that the resultant editor
* drive be one that transforms the reported hierarchy into a pristine tree
* of @a tgt_path at revision @a revnum. A @c NULL value for @a tgt_path
* will indicate that the editor should be driven in such a way as to
* transform the reported hierarchy to revision @a revnum, preserving the
* reported hierarchy.
*
* @a text_deltas instructs the driver of the @a editor to enable
* the generation of text deltas.
*
* @a ignore_ancestry instructs the driver to ignore node ancestry
* when determining how to transmit differences.
*
* @a send_copyfrom_args instructs the driver to send 'copyfrom'
* arguments to the editor's add_file() and add_directory() methods,
* whenever it deems feasible.
*
* Use @a authz_read_func and @a authz_read_baton (if not @c NULL) to
* avoid sending data through @a editor/@a edit_baton which is not
* authorized for transmission.
*
* @a zero_copy_limit controls the maximum size (in bytes) at which
* data blocks may be sent using the zero-copy code path. On that
* path, a number of in-memory copy operations have been eliminated to
* maximize throughput. However, until the whole block has been
* pushed to the network stack, other clients block, so be careful
* when using larger values here. Pass 0 for @a zero_copy_limit to
* disable this optimization altogether.
*
* @note Never activate this optimization if @a editor might access
* any FSFS data structures (and, hence, caches). So, it is basically
* safe for networked editors only.
*
* All allocation for the context and collected state will occur in
* @a pool.
*
* @a depth is the requested depth of the editor drive.
*
* If @a depth is #svn_depth_unknown, the editor will affect only the
* paths reported by the individual calls to svn_repos_set_path3() and
* svn_repos_link_path3().
*
* For example, if the reported tree is the @c A subdir of the Greek Tree
* (see Subversion's test suite), at depth #svn_depth_empty, but the
* @c A/B subdir is reported at depth #svn_depth_infinity, then
* repository-side changes to @c A/mu, or underneath @c A/C and @c
* A/D, would not be reflected in the editor drive, but changes
* underneath @c A/B would be.
*
* Additionally, the editor driver will call @c add_directory and
* and @c add_file for directories with an appropriate depth. For
* example, a directory reported at #svn_depth_files will receive
* file (but not directory) additions. A directory at #svn_depth_empty
* will receive neither.
*
* If @a depth is #svn_depth_files, #svn_depth_immediates or
* #svn_depth_infinity and @a depth is greater than the reported depth
* of the working copy, then the editor driver will emit editor
* operations so as to upgrade the working copy to this depth.
*
* If @a depth is #svn_depth_empty, #svn_depth_files,
* #svn_depth_immediates and @a depth is lower
* than or equal to the depth of the working copy, then the editor
* operations will affect only paths at or above @a depth.

*
* Calling @a (*editor)->abort_edit aborts the commit, and will also

/** Revision Access Levels
*
* Like most version control systems, access to versioned objects in
* Subversion is determined on primarily path-based system. Users either
* do or don't have the ability to read a given path.
*
* However, unlike many version control systems where versioned objects
* maintain their own distinct version information (revision numbers,
* authors, log messages, change timestamps, etc.), Subversion binds
* multiple paths changed as part of a single commit operation into a
* set, calls the whole thing a revision, and hangs commit metadata
* (author, date, log message, etc.) off of that revision. So, commit
* metadata is shared across all the paths changed as part of a given
* commit operation.
*
* It is common (or, at least, we hope it is) for log messages to give
* detailed information about changes made in the commit to which the log
* message is attached. Such information might include a mention of all
* the files changed, what was changed in them, and so on. But this
* causes a problem when presenting information to readers who aren't
* authorized to read every path in the repository. Simply knowing that
* a given path exists may be a security leak, even if the user can't see
* the contents of the data located at that path.
*
* So Subversion does what it reasonably can to prevent the leak of this
* information, and does so via a staged revision access policy. A
* reader can be said to have one of three levels of access to a given
* revision's metadata, based solely on the reader's access rights to the
* paths changed or copied in that revision:
*
* 'full access' -- Granted when the reader has access to all paths
* changed or copied in the revision, or when no paths were
* changed in the revision at all, this access level permits
* full visibility of all revision property names and values,
* and the full changed-paths information.
*
* 'no access' -- Granted when the reader does not have access to any
* paths changed or copied in the revision, this access level
* denies the reader access to all revision properties and all
* changed-paths information.
*
* 'partial access' -- Granted when the reader has access to at least
* one, but not all, of the paths changed or copied in the revision,
* this access level permits visibility of the svn:date and
* svn:author revision properties and only the paths of the
* changed-paths information to which the reader has access.
*
