avoid too generic identifiers to avoid possible clash with big apps

[Alexey-T]

const
  DEFAULT_DEPTH    = TJsonReader.DEF_DEPTH;
  DEFAULT_BUF_SIZE = TJsonReader.DEF_BUF_SIZE;

e.g. add some prefix to them.

Could you please clarify what you are talking about?

[Alexey-T]

big app (many units) may have var with name DEFAULT_BUF_SIZE. so better to rename your const to e.g. lgDefaultBufSize.

These constants were already part of the TJtdEntity class before I saw your message.

[Alexey-T]

better to rename these 2 consts. but you are the boss.
