Message:

ASSERT that a sessionID is valid when encoding it
​https://bugs.webkit.org/show_bug.cgi?id=199302

Reviewed by Darin Adler.

Source/WebCore:

For IDBValue, instead of encoding an invalid session ID, encode a boolean that tells there is no sessionID.
For IDBRequestData, keep track of whether there is an IDBDatabaseIdentifier
and encode/decode accordingly to not encode an invalid sessionID.
No observable change of behavior.

• Modules/indexeddb/IDBValue.h:

(WebCore::IDBValue::sessionID const):
(WebCore::IDBValue::encode const):
(WebCore::IDBValue::decode):

• Modules/indexeddb/shared/IDBRequestData.cpp:

(WebCore::IDBRequestData::isolatedCopy):

• Modules/indexeddb/shared/IDBRequestData.h:

(WebCore::IDBRequestData::databaseIdentifier const):
(WebCore::IDBRequestData::decode):

Source/WebCore/PAL:

ASSERT that a sessionID is valid at encoding/decoding time.

• pal/SessionID.h:

(PAL::SessionID::encode const):
