DWDS/Dialing Concordance Code

+ preparing for v2.2.5 release

* added new method CStringIndexator::IndexTokenFixLongColumns() for fallback repair of "greedy" tokens at indexing time
+ implicitly called by CStringIndexator::IndexOneToken() for overlong lines if new bool param tryFixErrors is true
+ tryFixErrors param is populated from CConcIndexator::m_bResumeOnIndexErrors on IndexOneToken() calls
+ truncates only "greedy" columns (those using more than MaxLen/nCols bytes)
+ truncates each "greedy" column indepdently, proportionate to its "greediness"
(the number of bytes by which its length exceeds MaxLen/nCols)
+ emits console warnings about truncation of line and each truncated column when invoked

replaced various byte-length constants '4096' with DDC_STATIC_BUFLEN

* Changelog tweaks

v2.2.5-pre1
* fixed weird fatal "ERROR: CheckOccurrences failed! occurrences are not sorted" error for pathologically long token lines
+ v2.1.25 built a consistent index and emitted warnings, but assigned partially indexed file data to *next* corpus file
+ v2.1.26-delwin and later throw this error at end of indexing ("return-bool" -> throw/catch)
* failed document indexing now initiates a rollback of in-memory index buffers via net methods CConcIndexator::RollbackIndexOneFile(), CIndexSetForLoadingStage::RollbackLoadIndex()
+ fixes "orphaned" token data as produced by v2.1.25
* exceptions from CConcIndexator::IndexOneTableTextArea(), CConcIndexator::IndexOneFile() should now be propagated to console and to *._error_log file

+ tagged ddc-2.2.4

* ddc v2.2.4 release cleanup

+ tagged ddc-2.2.4-rc1

+ tagging v2.2.4-rc1

+ query-lexer fine-tuning for negative dates (interference from fixes for mantis #19051 "6-er")
