Support multiple primary functions in a single snapshot. (#1797)

Browse Source 
This patch adds an extension to snapshots which allows storing
multiple position independent primary functions in a single
snapshot data. A new application called jerry-snapshot is
added to the project to manage snapshots. Currently the only
option is merging snapshots.
