This patch:
* Moves config files from /usr/local/mariadb/columnstore/etc to
ENGINE_SYSCONFDIR/columnstore (ENGINE_SYSCONFDIR is /etc by default)
* Sets a define called MCSSYSCONFDIR whic contains the
ENGINE_SYSCONFDIR compile time setting
* Modifies scripts and code to use the new paths
* Removes a whole bunch of files we don't use
With 1.1 we have removed libdrizzle and used MariaDB's client library
instead for both CrossEngine and QueryStats. Unfortunately MariaDB 10.2
has two client libraries which have different structs with the same
name. When QueryStats was running inside the ColumnStore plugin this
symbol conflict was causing a crash.
The server's built-in client API has several different and several
missing functions so some additions to sm.cpp were made to fill the
gaps.
This patch does the following:
* Make sure that libmariadb is only linked to executables, not the
ColumnStore Plugin (to avoid symbol conflicts). Note that all
executables that link to CrossEngine and/or QueryStats need to link to
libmariadb to avoid missing symbol issues.
* Use the server's built-in client API for QueryStats when run in the
plugin
* Replace missing server built-in client API calls in sm.cpp (this is
for QueryStats and CrossEngine to keep the dynamic linker happy)
* Fixes issue where using 'localhost' as the MariaDB Server hostname
would fail in QueryStats.
This does the following:
* Switch resource manager to a singleton which reduces the amount of
times the XML data is scanned and objects allocated.
* Make the I_S tables use the FE implementation of the system catalog
* Make the I_S.columnstore_columns table use the RID list cache
* Make the extentmap pre-allocate a vector instead of many small allocs
Remove generated Makefiles
Update Makefile.am to specify RPATH as a subdirectory of --prefix
Remove configure artifacts such as config.log, config.h, etc
Remove unneeded backup files (files ending in tilde ~)
