Remove debug msgs

[Martin-Zeithaml]

Problem

Some C functions has debug messages, which is fine. But:

• Incorrect encoding makes it difficult to read
• When fails as javascript call, it should respect configmgr trace level and some message format
• Deleting these messages is the most simple solution

ChangeTag

zos.changeTag prints garbage when fails.

Without fix

��/��ʀ�/�%������ǀ���>?�����zos.changeTag()=-1
��/��ʀ�/�%������ǀ���>?�����zos.changeTag(null)=-1
��/��ʀ�/�%������ǀ���>?�����zos.changeTag(undefined)=-1

��/��ʀ�/�%������ǀ���>?�����zos.changeTag(./file, which does not exit,250000)=-1

With fix

zos.changeTag()=-1
zos.changeTag(null)=-1
zos.changeTag(undefined)=-1
zos.changeTag(-12)=-1
