TODO
* libfdata next search keep going on a key match?

* fix flaky test for System_Search_AutoSummary (one byte off?)
* pyesedb
  - null value support
  - long value: add data size support
* refactor libesedb_record_get_value_binary_data_size and

Windows search:
* improve windows_search_decompress_byte_indexed_compressed_data

File format
* where is the root object defined? or is it implied to be object 1?
* compressed table, column, index names ?
* page flags
  - 0x0400, 0x0800, 0x8000
* tagged values
  - flag 0x4000
* multi value offsets
  - flag 0x8000

* (revision 0x11) extended page header
* what about the first byte in 7-bit ascii compressed data
* codepage 1200 string in Exchange EDB starts with 0xff 0xff
* streaming file
  - only consists of ESEDB header with paged streamed data,
    how to reconstruct streams ?

Deployment:
* update configure
  - improve libfdata detection
  - improve libfguid detection
  - improve libfwnt detection
* update manuals
  - add esedbexport.1

Performance
* create data definition tree in page tree for faster lookup of keys
  keep list for sequential access (B+-tree)
* create a UTF-8 version of run-length compressed UTF-16 string decompression function
* use register alignment for key comparison
* optimize libesedb_checksum_calculate_little_endian_ecc32

Test suite:
* windows search: work on index-based compression
  - create test program to validate output

Notes
* create a root page table instead?
  - no
* read catalog data type defintions and convert them into column definitions?
  - no
