5696adb5ec Validate the u4_entropy_coding_mode field
Previously, if this field wasn't set, the invalid coding mode
could lead to crashes later.

18e256879b Remove the now unused stride field from the set dimensions struct
Since 90a3904fd3 and d020be5ac7, this field doesn't have any actual
effect - the strides are taken from the input pictures.

cc87241e79 Don't declare variables after statements
This fixes building with compilers that are strict about the pre-C99
rule about having all variable declarations before statements.

517e0627ef Allow setting profile IV_PROFILE_MAIN
Now once that the encoder supports the main profile, allow it to
be set in the IVE_CMD_CTL_SET_PROFILE_PARAMS request.

The actual profile value set here is ignored in practice, but
at least allow setting it to main.

d2d469e520 Added check for minimum output buffer size.
Changed macro specifying the minimum size required for output buffer.

Added an error check on the size allocated for output buffer.

8588303afa Added code to handle cases with qp less than 10
When qp goes less than 10, all I16x16 mode evaluations
are disabled and I4x4 evaluations are enabled irrespective
of preset. This will ensure that the residual will not
exceed the supported range of entropy

Minimum Qp cannot be set less than 4 now. When QP goes lesser,
the residual may exceed the supported range even with I4x4 enabled.

6cb6772805 Reduced memory requirements.
Buffer allocation is based on minimum level required for the
input resolution rather than the input max level.

Number of maximum context sets can be set to 1 to reduce
memory usage.

Added a macro ENC_MIN_PU_SIZE for minimum size of
inter prediction unit supported by encoder.

Changed the maximum constraint on number of MBs for NMB
processing to width in Mbs.

d020be5ac7 Remove the codec level stride field
This field isn't used at the moment at all. The public field
ive_ctl_set_dimensions_ip_t.u4_strd is kept to avoid breaking
other calling code, although it doesn't have any actual function
any longer.

afe8d03624 Force regenerating the header via i4_gen_header instead of i4_header_mode
If i4_header_mode is set (without the caller explicitly requesting it),
the next frame to be encoded will be missed altogether (when only
a header is output).

Instead force a header to be generated prepended to the next frame.
If the caller explicitly requests header mode, it will be output
in a separate call.

fc508f2e87 Fix an overread in the slice map
After incrementing the macroblock position in ih264e_update_proc_ctxt,
the slice index of the next macroblock is read. The value that is read
isn't actually used, but make sure that the array is large enough to
avoid overreads.
