      Use intra_ext_tx_cdf when coding tx_type. · 72762a28
      Nathan E. Egge authored
      When building with --enable-daala_ec, the tx_type for intra blocks can be
       coded using the CDFs that are updated once per frame.
      This patch converts a tx_type symbol to be coded with aom_write_symbol()
       and aom_read_symbol() that was missed in f3e8e267.

      Bit accounting. · 6048d052
      Michael Bebenita authored
      This patch adds bit account infrastructure to the bit reader API.
      When configured with --enable-accounting, every bit reader API
      function records the number of bits necessary to decoding a symbol.
      Accounting symbol entries are collected in global accounting data
      structure, that can be used to understand exactly where bits are
      spent (http://aomanalyzer.org). The data structure is cleared and
      reused each frame to reduce memory usage. When configured without
      --enable-accounting, bit accounting does not incur any runtime
      overhead.
      
      All aom_read_xxx functions now have an additional string parameter
      that specifies the symbol name. By default, the ACCT_STR macro is
      used (which expands to __func__). For more precise accounting,
      these should be replaced with more descriptive names.
