[reltool] Update state and tables consistently for all types of config changes
OTP-9794
OTP-9968
The main idea behind the data structure in reltool_server is that the
state shall reflect what is explicitly configured, and the tables
shall contain this configuration plus everything that is derived. In
some cases, however, this was not the complete truth:
* the application table was never read
* the module table was never updated on undo
* the state contained a lot more than what was explicitly configured
This commit re-writes major parts of the reltool_server for the sake
of unifying the way the state and tables are updated:
* The list of applications in the state now only contains those
applications and modules for which there are explicit settings in
the configuration (given at startup or changed from the GUI)
* When changing any bit of the configuration, the tables are always
emptied and every part is derived again from the configuration found
in the state
* All configuration changes now cause a re-read of the file system,
meaning that if something has changed in the file system it will be
reflected in the result of the configuration change. This is the
case even if no file system related configuration is changed
(e.g. root dir or lib dirs)
(*POSSIBLE INCOMPATIBILITY*)
* Requests for applications and modules from the GUI now always read
the tables, not the state
* When loading a new configuration file via the GUI, the old
configuration is completly scratched, and only the new is valid
(*POSSIBLE INCOMPATIBILITY*)
* The handling of escripts which include archives of applications is
changed to always produce one #app record for the escript in
addition to one for each inlined application. All modules are listed
as parts of the inlined application where it belongs and not as part
of the escript's #app record. This is a temporary solution which
will be modified and improved.
The following bugs are corrected by this commit:
* Loading a config which contains an escript via the GUI menu did not
produce the same #app record as when loading the same configuration
at reltool start. Paths, version and label could differ.
* Loading config with same escript (source) twice caused reltool to
add same module twice in #app.mods
* Loading config with same escript (inlined beam) twice caused reltool
to fail saying module is included by two different applications
* Loading config which in addition to an existing escript also adds
another escript for which the name sorts before the existing one
would cause reltool to fail saying "Application name clash"
