This should be handled fine now by .dir-locals.el, so need to carry that
stuff in every file.

Go over the entries in the map and check that they make sense.
Tests are added. In the future we might want to do additional
checks, e.g. verifying that the error names are in the expected
format.

errno_from_name used an unusual return convention where 0 meant
"not found". This tripped up config_parse_syscall_errno(),
which would treat that as success. Return -EINVAL instead,
and adjust bus_error_name_to_errno() for the new convention.
Also remove a goto which was used as a simple if and clean
up surroudning code a bit.

Sort the includes accoding to the new coding style.

string-util.[ch]
There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.

Replace ENOTSUP by EOPNOTSUPP as this is what linux actually uses.

Stuff in src/shared/ should not use stuff from src/libsystemd/ really.

The ELF magic cannot work for consumers of our shard library, since they
are in a different module. Hence make all the ELF magic private, and
instead introduce a public function to register additional static
mapping table.

__attribute__((used)) is not enough to force static variables to
be carried over to a compiled program from a library. Mappings defined
in libsystemd-shared.a were not visible in the compiled binaries.
To ensure that the mappings are present in the final binary, the
tables are made non-static and are given a real unique name by which
they can be referenced.
To use a mapping defined not in the local compilation unit (e.g. in
a library) a reference to the mapping table is added. This is done
by including a declaration in the header file.
Expected values in test-engine are fixed to reflect the new mappings.

Depending on the link order, holes might appear in the body of
the sd_bus_errnomap section. Ignore them.
Adds a simple test to print the table to help with debugging such
issues in the future.

This allows custom "name" ↔ errno mappings to be registered.
Tables from all compilation units are concatenated.

sd_bus_error, just go on
sd_bus_error_setfv() must initialize the sd_bus_error value to some
sensible value and then return a good errno code matching that. If it
cannot work at all it should set the error statically to the OOM error.
But if it can work half-way (i.e. initialize the name, but not the
message) it should do so and still return the correct errno number for
it.

Check for OOM situations when vasprintf() returns < 0 in bus_error_setfv().

strerror_r does not return null here and even if it did we would have
problems already at the preceding strlen call.
Found by coverity. Fixes: CID#1237770

We still only produce on .so, but let's keep the sources separate to make things a bit
less messy.
