Jackson 2.6.0 发布，高性能的 JSON 处理

Jackson 2.6.0 正式发布，此版本主要有以下更新：

#137: Allow filtering content read via `JsonParser` by specifying `JsonPointer`;

uses new class `com.fasterxml.jackson.core.filter.FilteringParserDelegate`

(and related, `TokenFilter`)

#177: Add a check so `JsonGenerator.writeString()` won't work if `writeFieldName()` expected.

#182: Inconsistent TextBuffer#getTextBuffer behavior

(contributed by Masaru H)

#185: Allow filtering content written via `JsonGenerator` by specifying `JsonPointer`;

uses new class `com.fasterxml.jackson.core.filter.FilteringGeneratorDelegate`

(and related, `TokenFilter`)

#188: `JsonParser.getValueAsString()` should return field name for `JsonToken.FIELD_NAME`, not `null`

#189: Add `JsonFactory.Feature.USE_THREAD_LOCAL_FOR_BUFFER_RECYCLING` (default: true), which may

be disabled to prevent use of ThreadLocal-based buffer recyling.

(suggested by soldierkam@github )

#195: Add `JsonGenerator.getOutputBuffered()` to find out amount of content buffered,

not yet flushed.

(requested by Ruediger M)

#196: Add support for `FormatFeature` extension, for format-specifc Enum-backed

parser/generator options

- Minor improvement to construction of "default PrettyPrinter": now overridable by data format

modules

- Implement a new yet more optimized symbol table for byte-backed parsers

- Add `JsonParser.Feature.IGNORE_UNDEFINED`, useful for data formats like protobuf

- Optimize writing of String names (remove intermediate copy; with JDK7 no speed benefit)
