When og_dbi_open cannot open a connection during schema update, then
ogServer crashes.
og_dbi_open returns NULL when it cannot open a DB connection.
Do not use dbi variable if og_dbi_open is unable to open a DB
connection.
Add syslog message when database schema couldn't be updated.
Add foreign key "identornos" from table "entornos" to table
"ordenadores".
A row in table "entornos" represent a valid ogServer address.
Multiple ogServer valid addresses can exist when running several
instances or a single ogServer instance is exposed to different networks.
Can't delete rows in "entornos" table nor update their id (primary
key) if the row has any associated clients ({ON UPDATE/ON DELETE} RESTRICT).
Allows assigning different but valid ogServer IPs to clients.
Enabling support for multiple instances of ogServer (e.g: load balancing) or
exposing a single ogServer instance to different networks (e.g: VLAN).
Look up for the valid ogServer IP of a given client when changing a
client's mode (og_set_client_mode).
Determines valid ogServer IP using a JOIN statement.
JOIN entornos USING(identorno)
Reuses the fetched ip using a statement variable.
@serverip:=entornos.ipserveradm
For example, for a two VLAN setup:
vlan1 ogserver: 192.168.56.10
vlan2 ogserver: 192.168.57.10
The "entornos" table should look like:
identorno ipserveradm ...
--------- ----------- ...
1 192.168.56.10 ...
2 192.168.57.10 ...
And computers in the "ordenadores" table might look like:
idordenador identorno ...
---------- --------- ...
1 1 ...
2 1 ...
3 2 ...
4 2 ...
... ... ...
Additionally, splits the SQL query for better readability.

Add ogServer support for parsing and storing in the DB disk type data
from ogClient refresh response.
See also commits with #1037 in ogClient and WebConsole repo.
Add foreign keys (version 1 introduced innoDB as default db engine)
allowing cascade deletions for some tables:
- perfilessoft_softwares
If a software profile or a software component is deleted, the
corresponding row in this table will be deleted too.
- ordenadores_particiones
If a computer or a partition is deleted from the DB, delete the
corresponding row inside this table.
- aulas
If the center the room is in is removed, delete the room too.
- ordenadores
If the room in which a computer is in is removed, the computer
will be deleted accordingly.
We should take into account that this schema superseeds some code
regarding deletions inside WebConsole that probably are not needed any
more, at least for the tables mentioned.
(See admin/WebConsole/gestores/relaciones/*.php in OpenGnsys repo)
This patch adds database schema management capabilities to ogServer:
- ogServer now tracks the version of its database schema, if no version
is detected, creates a 'version' table with a single row starting at 0.
- ogServer can upgrade its database schema to a newer version if
detected. (ogServer ships required SQL commands to do so)
If ogServer is unable to upgrade the schema at startup (if needed be) it
*will not* start.
Defines schema update v1 which upgrades database engine tables of
ogServer database (usually named 'ogAdmBD') from myISAM to innoDB.
