  tidy: Silence false positive memory leak warnings.

There are a couple of places that clang-tidy raises warnings that
newly allocated objects are leaked.  In all of these cases, the
objects is placed on a list, either inside the constructor or in
another functions.

  tidy: Fix a memory leak in mythtv-setup.

This program allocates wither a QCoreApplication object or a
QApplication object using the "new" operator.  Clang-tidy flags this
as a memory leak as there is no corresponding "delete" operator.  (Its
there, just hidden elsewhere.)  This can't be converted to RAII
because the application object would get cleaned up too soon, so move
the explicit delete into the main function instead of having it
elsewhere.

This program allocates the QApplication object using the "new"
operator.  Clang-tidy flags this as a memory leak as there is no
corresponding "delete" operator.  (Its there, just hidden elsewhere.)
Convert this to RAII so that the delete happens automatically in the
stack cleanup and clang-tidy understands that the object is deleted.

There are also two other memory leaks that are fixed with a
combination of RAII and unique pointers.

  tidy: Fix potential null dereference in mythfrontend.

Clang-tidy is reporting a potential null dereference in the loadPage
function.  Two of the three places in this function that dereference
the record variable test its validity before dereferencing it.  Add a
validity check to the third place the variable is dereferenced.

  tidy: Fix a potential memory leaks in recordeingprofile.cpp.

The VideoCompressionSettings constructor has a memory leak when the
dynamic_res variable is set to false.  The code unconditionally
allocates three data structures, and uses all of them when dynamic_res
it true, but only uses one of them when dynamic_res is false.  Add
code to the false case to delete the two unused structure.

Use unique pointers to fix a couple of potential memory leaks flagged
by clang-tidy.
