Checkout a working copy from a repository.

@param[out] result_rev If non-NULL, the value of the revision checked out from the repository. @param[in] URL The repository URL of the checkout source. @param[in] path The root of the new working copy. @param[in] peg_revision The peg revision. @param[in] revision The operative revision. @param[in] depth The depth of the operation. If #svn_depth_unknown, then behave as if for #svn_depth_infinity, except in the case of resuming a previous checkout of @a path (i.e., updating), in which case use the depth of the existing working copy. @param[in] ignore_externals If @c TRUE, don’t process externals definitions as part of this operation. @param[in] allow_unver_obstructions If @c TRUE, then tolerate existing unversioned items that obstruct incoming paths. Only obstructions of the same type (file or dir) as the added item are tolerated. The text of obstructing files is left as-is, effectively treating it as a user modification after the checkout. Working properties of obstructing items are set equal to the base properties.
If @c FALSE, then abort if there are any unversioned obstructing items. @param[in] ctx The standard client context, used for authentication and notification. @param[in] pool Used for any temporary allocation.

@return A pointer to an #svn_error_t of the type (this list is not exhaustive):
#SVN_ERR_UNSUPPORTED_FEATURE if @a URL refers to a file rather than a directory;
#SVN_ERR_RA_ILLEGAL_URL if @a URL does not exist;
#SVN_ERR_CLIENT_BAD_REVISION if @a revision is not one of #svn_opt_revision_number, #svn_opt_revision_head, or #svn_opt_revision_date.
If no error occurred, return #SVN_NO_ERROR.

@since New in 1.5.
