More updates to common verbs infrastructure: * Moved "check basics" sanity check from openib BTL to common/verbs (which also allows us to have openib ''not'' include <infiniband/driver.h>, which is a Very Good Thing) * Add new ompi_common_verbs_qp_test() function, which tests to see whether a device supports RC and/or UD QPs. The openib BTL now uses this function to ensure that the device supports RC QPs. * Rename ompi_common_verbs_find_ibv_ports() to be ompi_common_verbs_find_ports() -- the "ibv" was redundant. * Re-work ompi_common_verbs_find_ports() to use ompi_common_verbs_qp_test() instead of testing for RC/UD QPs itself * Add bunches of opal_output_verbose() to the find_ports() routine (to help diagnosing connectivity problems -- imaging running with --mca btl_base_verbose 10; you'll see all the find_ports() test results) * Make ompi_common_verbs_qp_test() warn if devices/ports are supplied in the if_include/if_exclude strings that do not exists (quite similar to what the openib BTL does today). * Add ompi_common_verbs_mca_register() function, which registers common verbs MCA params. It will also register MCA param synonyms for thse MCA params to upper-level components (e.g., btl_<upper-level-component>_<the-mca-param>). * common_verbs_warn_nonexistent_if: warn if if_include/if_exclude-specified devices or ports do not exist. This commit was SVN r27332.

MCA/base: Add new MCA variable system Features: - Support for an override parameter file (openmpi-mca-param-override.conf). Variable values in this file can not be overridden by any file or environment value. - Support for boolean, unsigned, and unsigned long long variables. - Support for true/false values. - Support for enumerations on integer variables. - Support for MPIT scope, verbosity, and binding. - Support for command line source. - Support for setting variable source via the environment using OMPI_MCA_SOURCE_<var name>=source (either command or file:filename) - Cleaner API. - Support for variable groups (equivalent to MPIT categories). Notes: - Variables must be created with a backing store (char **, int *, or bool *) that must live at least as long as the variable. - Creating a variable with the MCA_BASE_VAR_FLAG_SETTABLE enables the use of mca_base_var_set_value() to change the value. - String values are duplicated when the variable is registered. It is up to the caller to free the original value if necessary. The new value will be freed by the mca_base_var system and must not be freed by the user. - Variables with constant scope may not be settable. - Variable groups (and all associated variables) are deregistered when the component is closed or the component repository item is freed. This prevents a segmentation fault from accessing a variable after its component is unloaded. - After some discussion we decided we should remove the automatic registration of component priority variables. Few component actually made use of this feature. - The enumerator interface was updated to be general enough to handle future uses of the interface. - The code to generate ompi_info output has been moved into the MCA variable system. See mca_base_var_dump(). opal: update core and components to mca_base_var system orte: update core and components to mca_base_var system ompi: update core and components to mca_base_var system This commit also modifies the rmaps framework. The following variables were moved from ppr and lama: rmaps_base_pernode, rmaps_base_n_pernode, rmaps_base_n_persocket. Both lama and ppr create synonyms for these variables. This commit was SVN r28236.
