in some configurations MSVS will define _off_t / off_t in wchar.h; the
former is used locally while the latter is for compatibility. this
change overrides off_t as in the past and sets _OFF_T_DEFINED to prevent
a clash in types.

For real-time mode under cbr, this increases the gain (5-10%)
for speed 5 (none/little change for 6), on vc-clips.

Turns off the DISABLE_RC_LONG_TERM_MEM macro and makes other changes
in the way the bits are updated, to make 2-pass rate control track
target bitrates closer.

Parameterize the frame level quantization index used in non-RD
coding flow with cbr.

This commit reduces the frequency of frames using finer quantizer
in non-RD coding flow, and slightly tune up the quantizer resolution
when used. It provides 1.7% compression gains in speed -5 at no speed
difference.

Temporary revert.
Problems with conflicting definitions of type off_t
in MSVC builds that need resolving.

c:\Program Files (x86)\
  Microsoft Visual Studio 9.0\VC\include\wchar.h(479) :
  "error C2371: 'off_t' : redefinition; different basic types
c:\on2experimental\libvpx\tools_common.h(26) :
   see declaration of 'off_t'"

This reverts commit 92a4c591.

The new tolerance is a little higher than before (especially
for kf/gf/arf) so this change gives an encode speed up
for some clips up for speeds 0-2.

This code/setting was actually not used (since speed features were not set on first frame,
until a recent change) and should be removed.

In CBR mode, the q value for the first frame can be controlled by setting
the target size via the parameters rc_buf_initial_sz (and max_intra_size_pct).
