* IdentityCacheable
new interface required of objects stored in ObjectIdentityCaches
* IdentityCacheableWrapper
wrapper for storing arbitrary objects in ObjectIdentityCaches
* ObjectIdentityCache
keys now always Strings
values now always IdentityCacheables
new dirtyKey() method to ensure a key is persisted
* ObjectIdentityBdbCache, ObjectIdentityMemCache
update for new ObjectIdentityCache shape; still using legacy GC magic

alternate implementation relying on dirtying to ensure persistence
use Guava library MapMaker for soft memMap; capped dirtyMap

up expectedConcurrency default to 64

* CrawlURI
MAX_HOPS_DISPLAYED constant, 50
build new CrawlURI pathFromSeed value via extendHopsPath, which shows only MAX_HOPS_DISPLAYED hops, and precedes string with int value of hops unshown
* CrawlURITest
test for extendHopsPath
* ExtractorJS
apply JS literal string deescaping before interpretation as link
* ExtractorJSTest
3 basic tests, including one for this issue
* Link
provide logging and fallback for case where via may be null; risk identified in creation of test cases could present again if a '.js' file is ever provided as a (via-less) seed
addStats() - use putIfAbsent() to avoid race conditions; move
creation of stats map to constructor to avoid another race condition
* WARCWriter.java
switch back to thread-unsafe data structures for stats since object is used
in one thread at a time according to javadoc
processing is finished.

getReplayCharSequence() - remember ReplayCharSequence, obtain new one if
none remembered or remembered has been closed
endReplays() - close replayCharSequence

delegate record-ID generation

bytes, and (possibly compressed) size on disk
* WARCWriterProcessor.java
keep totals and write report to processors-report.txt
new property textSource, an org.archive.io.ReadSource, allowing
specification inline in cxml as well as in external file
* profile-crawler-beans.cxml
commented out clauses demonstrating use of textSource
* DecideRuleSequence.java
- use Spring Lifecycle start() to initialize logToFile
- inject logger module as SimpleFileLoggerProvider, since we're in
heritrix-modules and don't have access to CrawlerLoggerModule from
heritrix-engine

- implement SimpleFileLoggerProvider
- setupSimpleLog() - use 'T' instead of '+' between date and time in
timestamp
* SimpleFileLoggerProvider.java
new interface with one method, setupSimpleLog()
* Scoper.java
do not call scope.start()/scope.stop(), these are handled using Spring
Lifecycle now
* DecideRule.java
remove unused, unneeded start()/stop()
* (many)
distinction between these two constant-collecting classes was fuzzy (to the point that they already referred to each other), and they were both in same subproject/package already as well; so, merged constants into the larger, older class

use recycled matchers via TextUtils

use ArrayList and indexed access rather than LinkedList and iterator instances
setting "independentExtractors" - when enabled, extractors run regardless of
whether other extractors have run
* profile-crawler-beans.cxml, AbstractFrontier.java, ExtractorParameters.java,
Extractor.java
new setting independentExtractors

shouldProcess() - respect independentExtractors

adjust for new never-timeout behavior
* ARCWriterPoolProcessor.java WARCWriterPoolProcessor.java
adjust constructor calls

replace poolMaxWaitMs (which caused eventual complete timeout from waiting for writer) with maxWaitForIdleMs, a much smaller value which only controls how long a thread waits for an reusable writer before considering creating a new one.
