[PATCH v3 0/3] tools/ocaml: Stabilize domain_getinfo for Oxenstored

[Andrii Sultanov <andrii.sultanov@xxxxxxxxx>]

Changes from V2:

* Drop the upstreamed "Build infrastructure" commit
* Split the last commit into two: Loading the plugin in oxenstored and
switching to it
* Remove configure and paths.m4 defines as suggested.
* Reformat files appropriately
* Rename all instances of 'xenstoredglue', 'xenstored_glue', 'xsglue' to
'xsd_glue' for consistency
* Remove _v1 suffix from all static functions
* Remove leftover #defines left unused by the previous changes
* Fix inconsistent tabs/spaces usage, added blank lines where appropriate.
* Define the 'xsd_glue_failwith' macro as suggested
* Remove first_domain argument in 'domain_getinfolist' function
* Remove unnecessary memory allocation alignment code in
'domain_getinfolist'
* Improve error handling in 'domain_getinfolist' as suggested.
* Add SPDX license headers to new files.
