This update of tk and tcl to version 8.6.7 brings many improvements and fixes including,
but not limited to, the following highlights:

- Fix a bug in Itcl that was causing the floor tool to print lots of errors and abort.
  (bsc#903017)
- Fix a crash in asynchronous connection to hosts when no address is given.
- Fix possible crashes when closing multithreaded applications.
- Fix a memory leak in [history] destruction.
- Fix a crash in Tcl_ListObjReplace().
- Invalidate VFS mounts on sytem encoding change.
- Repair drifts in timer clock when calling Tcl_GetTime from tcl-clock module.
- Fix a crash when requesting too much character data in binary scan.
- Fix a memory leak when calling geturl from the http package.
- Fix an integer overflow in [lsort] on very long lists.
- Fix a memory leak when calling TclJoinPath.
- Fix a memory leak due to a reference cycle in foreach loops.
- Fix a crash caused by an optimization in the compilation of [string replace].
- Fix a memory corruption in assembler exceptions.
- Fix a crash due to [vwait] trace undo fail.
- Fix a crash when invoking [glob -path a].
- Fix a crash in [dict update] after using lassign in an item.
- Fix a crash in [chan configure -dictionary].
- Make it possible to specify different values for the -accept option when running multiple
  asynchronous http: requests without incurring in race conditions.
- Fix a crash when calling the [expr] command while the application is being traced.
- Avoid leaking memory in Tcl_ZlibInflate when running into error conditions.
- Fix some writes beyond buffer bounds.
- Fix a memory leak in array when unsetting keys from a proc.
- Fix a lock in forking a process under heavy multithreading.
- Fix a crash caused by an allocation overflow when parsing a very large expression.
- Many fixes and improvements to regexp engine from Postgres.
- Fix a segmentation fault due to an integer overflow in TranslateInputEOL().
- Fix multiple crashes in OO teardown.
- Stop crashes when extension var resolvers misbehave.
- Fix using [read] to read past the EOF so that it works on serial devices.
- Fix a regression causing a crash in [oo::class destroy].
- Fix a segmentation fault in mangled bytecode.
- Fix a hang in some [read]s of limited size in UTF-8 channels.
- Fix a segmentation fault in [array set] of traced array.

The following fixes might show some potential incompatibilities with existing software:
- Allow an empty command to be the target of an alias.
- Reconcile libtommath updates, purging some unused files.
- Handle invalid UTF-8 characters correctly in Tcl_UtfToUniChar() to prevent the injection
  of unexpected characters.
- Update Unicode data to 10.0
- Fix some problems in the compilation of [lreplace].
- Fix using parameters with spaces in error messages.
- Make it possible to use [namespace upvar] when the target variable is also a variable of
  the class.
- Change the default transfer encoding to gzip in the http package to be more compatible.
- Limit $... and bareword parsing to ASCII characters only.
