Harald Welte 04c881207f stats_test: Extend check to include test for counter group name mangling
In Change-Id Ifc6ac824f5dae9a848bb4a5d067c64a69eb40b56 we introduce
name mangling to replace any '.' in counter (group) names to be
converted to ':'. Let's test for this functionality explicitly as part
of the stats_test.

Harald Welte a7a5065385 Convert lib-internal rate_ctr from '.' separator to ':' separator
The rate_ctr.c code would do this mangling automatically, but let's
avoid using this from new versions of our code for
simplicity/explicitness.

Harald Welte ae510dc4a7 rate_ctr: Enforce counter (and ctr_group) names are valid identifiers
As rate counters are automatically exposed on the CTRL interface,
we need to make sure they don't contain special characters such as '.'
which are not permitted/supported by CTRL.

In order to be able to run old versions of osmocom programs with
libosmocore versions after this commit, we introduce some special
name mangling:  Any '.' in the names are replaced with ':' during
counter group registration, if valid identifiers can be obtained
this way.

Neels Hofmeyr b41b48e76a stats_test: fix mismatching osmo_stats_reporter->send_item signature
The function pointer expects the last arg as int64_t, stats_test.c uses
an int instead. Fix the argument type as well as the printf format for it.

Fixes this compiler warning seen on our FreeBSD build slave:

This tests uses a dedicated test reported to check several aspects of
the value reporting.
  - addition/removal of stats reporter
  - addition/removal of counters/items
  - setting of max_class
  - initial value flush
  - updating single counters/items
  - reporter retrieval
  - enable/disable

Jacob Erlbeck fc9533d6c4 stats: Add osmo_ name prefix to identifiers
Since the the stat_item and stats functions and data types are meant
to be exported, they get an osmo_ prefix.

[hfreyther: Prepended the enum values too. This was requested by

Jacob Erlbeck b27b352e93 stats: Use a global index for stat item values
Currently each stat item has a separate index value which basically
counts each single value added to the item and which can be used by
a reporter to get all new values that have not been reported yet.
The drawback is, that such an index must be stored for each stat
item.

This commit introduces a global index which is incremented for each
new stat item value. This index is then stored together with the item
value. So a single stored index per reporter is sufficient to make
sure that only new values are reported.

Jacob Erlbeck 9732cb4a92 stats: Add stat_item for value monitoring
This commit adds instrumentation function to gather measurement
and statistical values similar to counter groups.

Multiple values can be stored per item, which can be retrieved in
FIFO order. Getting values from the item does not modify its state to
allow for multiple independant backends (e.g. VTY and statd).

When a new value is set, the oldest value gets silently overwritten.
Lost values are skipped when getting values from the item.
