[PATCH v2 00/23] gitlab: Simplify the test script

[Simon Glass]

At present there are several things in the gitlab, travis and azure
scripts which work around limitations in buildman. With a few small
feature additions these can be removed.

This series adds some new features to buildman and simplifies the script:
- Option to run a single build in a specified output directory
- Allow ignoring warnings
- Removes a restriction on the build output directory

It also
- adds a way for test.py to use buildman for the --build option
- makes one change to azure since the same approach should be possible there
- fixes a few minor problems noticed in main and sandbox docs
- removes the -a buildman flag which serves no purpose

Note: I tested that this works OK on travis, gitlab and azure:
https://travis-ci.org/github/sglass68/u-boot/builds/662740008
https://gitlab.denx.de/u-boot/custodians/u-boot-dm/pipelines/2435
https://dev.azure.com/simon0972/u-boot/_build/results?buildId=3&view=results

There is something funny about azure - the test called
"Run binman, buildman, dtoc and patman testsuites" fails the 'buildman -t'
test but azure reports success.

Changes in v2:
- Add Fixes tag
- Add a comment about the obscure bash feature
- Add a new patch to avoid copying files into .bm-work/
- Add a new patch to drop the -a option
- Add a new patch to split travis building into two parts
- Add new patch to drop the repeated buildman call
- Convert this into an option, leaving the default as is
- Just drop the -E flag
- Leave in the repeated call to buildman
- Reword the commit message for clarity
- Update azure also
- Update travis, azure also
