GA release v1.0.40

Changes since 1.0.36: v1.0.36...v1.0.40

Notable:

• Fix to data integrity issue: corruption in timestamp(6) and datetime(6) microsecond values when smaller than 0.1sec, #452
• Fix to data integrity issue: kill on the master connection could cause a premature cut-over without all the rows being copied, #445
• Fix to data integrity issue: support for alter table .. change column X where X is a different letter case than original column, #447
• supporting tables that reach up to and including max length (64 characters), #451
• Hibernate on critical load: when critical-load-hibernate-seconds > 0, then the behavior of critical-load changes. Instead of panicking and bailing out with error, gh-ost enters hibernation. #424
• dml-batch-size is dynamic, supported up to 1000
• http-throttle outputs clearer throttle messahes
• http-throttle is freno aware and outputs clearer throttle messahes
• fix to critical-load hibernation check
• support for drop + add a column of same name (gh-ost will recognize the before/after columns to be unrelated)
• RDS documentation, thanks @jacobbednarz
• improved documentation, thanks @jessbreckenridge
• more...
