6b17a18893 Ensure the exercises use the canonical format
Add the check-exercises.py tool in the new tools directory.  It is used
to check that the exercises are correctly formatted, printing on stderr
the invalid ones and the diff in the unified format.

Update the exercises that don't use the canonical zig fmt format.

Update some patches that cause the generated zig file to be incorrectly
formatted.

b59bef29b9 ci: add a CI workflow
Add a new github workflow named CI.

Add a job named compat, checking that and old Zig compiler will not fail
with a compiler error, but instead will print an useful error message.

30db9d105a build: avoid intermixed messages on the same line
In same cases, the progress messages from the compiler are intermixed
with the messages printed by ZiglingStep.

This intermixing appears in two cases:
  - when printing, e.g., the message "Checking 0_arrays2.zig..."
  - when printing the compiler errors

Closes #230

c6e055dd83 build: don't print errors in ZiglingStep.eval
Move the code for printing compiler errors and messages to the new
ZiglingStep.printErrors method.

Call printErrors in the Zigling.doCompile method, both in the normal and
error flow.

When handling an error from the Zig IPC, add the case when the compiler
was unable to return the executable path.

Before using the IPC, the error was
  "The following command exited with error code 1"
now it is
  "The following command failed to communicate the compilation result"

b39c7e61ef build: restore compatibility support again
Commit e214c44 (build: update ZiglingStep to the new API) broke again
the compatibility support for old compilers, due to the use of the
multi-object for loop syntax.

Move the Zig IPC support code to src/ipc.zig.

Use the while statement, instead of the for statement.

e91c7a24f2 build: disable special case for zig build -Dhealed
The special case was added because it was used by the Eowyn github
workflow.

As a side effect, however, it prevents testing the normal case used by
users.

Disable it, until a better solution is found.

be782af7a3 build: restore compatibility support
Commit 0d56ba3 (build: restore the exercise chain) broke the
compatibility support for old compilers, due to the use of the
multi-object for loop syntax.

Use the normal for loop syntax; the change still keep the code readable.

Use the variable `n`, instead of `i`, when referring to the exercise
number; this will improve the readability.

c656536d3f build: simplify code and add tests
Simplify the code finding the exercise number from the exercise index,
when the -Dn option is set.  This is now possible since the exercise
numbers have no holes.

the correct order, and call it at the start of the build function.

Add tests, with 2 test cases.

d43f19ded8 build: add support for skipping exercises
Currently, exercises not working with the current Zig compiler are
commented. This is problematic, since the exercise key and exercise
index are no longer consistent.

Add the skip field to the Excercise struct.  Update ZiglingStep to
support it and add a new SkipStep step to support it when using the
standard build step.

67f369484c build: ensure the exercise links libc, when needed
When running, as an example, `zig build -Dhealed -Dn=93 test`, the build
fails, because the `test` step use the standard CompileStep, instead of
ZiglingStep.

Ensure that exercises using libc are correctly built.

1cf910fb51 build: enable full parallelism when -Dhealed is set
The eowyn.sh script is used in a github workflow, but after
commit 0d56ba3 (build: restore the exercise chain), the github action
will take more time to complete.

Enable full build parallelism, when -Dhealed is true and -Dn is null.
Use the standard CompileStep and RunStep, instead of ZiglingStep.

On my PC, this change reduces the build time by about 30%.

59e28987da build: restore the exercise chain
The new parallel build support in Zig broke the exercise chain, so that
each esercise check is no longer strictly serialized.

  1. Add the Dexno option, in order to isolate the chain starting from a
     named exercise from the normal chain, thus simplify the code.

     The current code have an additional issue: it added 4 x n steps,
     making reading the help message or the list of steps very hard.

     Add only the `install`, `uninstall`, `zigling`, `test` and `start`
     steps.  The last three steps match the old steps `n`, `n_test` and
     `n_start`.

     The default step is zigling (note the singular form).

     The `install` step override the builtin install step, showing a
     custom description and matches the old `n_install` step.
     The uninstall step was added for consistency, so that the
     description is consistent.

     Setup a new chain starting at `zig build -Dexno=n start` so that it
     is stricly serialized.

     The behavior should be the same as the old one.

  2. Handle the code for all the exercises separately.

     Add only the `ziglings step`, making it the default step, in
     addition to the install and uninstall steps.

     Setup a new chain starting at the first exercise, to that it is
     strictly serialized.

     The behavior should be the same as the old one.

The current code has a know issue: the messages from the ZiglingStep and
the ones from the compiler compilation progress are interleaved, but each
message is written atomically, due to the use of `std.debug.getStderrMutex()`.

Update the README.md file.

75a1600626 build: fix the description of the named_install step
Replace the description of the named_install step from
"Install {s} to zig-cache/bin" to "Copy {s} to prefix path".  The latter
has been adapded from the description of the builtin install step.

Ad an empty line before the build_step variable, in order to improve
readability.

45713ec8ab build: restore support for Zig 0.6.0
The version check for Zig 0.6.0 was incorrect since commit
971ab7f (Use a zig build script to run ziglings).

Move compatibility support to a separate file, in order to simplify
build.zig.

In case of incompatible version, exit with code 3 instead of 0, in order
to detect the case of failure in a test (to be implemented).

Remove the use of comptime when checking compatibility at the start of
the build function, since it is not necessary.

Closes #210.

dd15cb94fd build: make the logo a build step
