Update to ZDoom r1062:

- Rewrote myvsnprintf to use the StringFormat routines directly so that no
  additional memory needs to be allocated from the heap.
- Polyobject sounds now play from their lines, similar to the way sector
  sounds are handled.
- Why do polyobjects have a 3D start spot? Flattened it to 2D.
- Moved the sector sound origin calculation out of fmodsound.cpp and into
  s_sound.cpp so that the near sound limiting will use the correct sound
  location for deciding on neighbors.
- Removed the S_Sound() variant that allows for pointing the origin at an
  arbitrary point. It has been replaced with a variant that takes a polyobject
  as a source, since that was the only use that couldn't be rewritten with the
  other variants. This also fixes the bug that polyobject sounds were not
  successfully saved and caused a crash when reloading the game. Note that
  this is a significant change to how equality of sound sources is determined,
  so some things may not behave quite the same as before. (Which would be a
  bug, but hopefully everything still sounds the same.)
- Adjusted the noise debug table so that fractional volume levels do not
  run into the adjacent columns.
- Added a NullSoundRenderer so that most of the checks against a NULL GSnd
  can be removed.
- Fixed: Looping sounds must always successfully allocate a channel, even if
  it's only a pre-evicted channel.
- Added A_ClearReFire code pointer for weapons. Preferably A_WeaponReady should
  reset this counter but that can't be done due to unwanted side effects with
  existing weapons.
- Changed the 'scale' variable in CVAR(turbo) to double because the calculations
  depended on the current floating point precision setting and only worked properly
  when set to 'precise' in VC++.
