Feature/527 manifest improvement

[PengZheng]

This PR fixes #527 by adapting Felix's manifest parsing to Celix. The Felix approach has the following advantages:

• Memory Safe. Explicit memory writes are guaranteed to be within bound, and string is guaranteed to be null terminated.
• Efficient. It use only 512 B stack memory for ordinary manifest, while the previous implementation use 3.5 KB. Explicit memory allocation is avoided if possible.
• Easy to test. 100% coverage.

And manifest.c uses ERR for logging. Corresponding ERR logging interfaces are added to framework and C/C++ bundle context. Along the way, it also improves ERR by avoiding thread specific storage allocation triggered by any read operation. That is, TSS will be allocated only by ERR write operations: celix_err_pushf/celix_err_push.
