This was a function from the original require, but it wasn't even
ever used there...

This was only used for some older location to look for libraries and other
files. We do not use that in our packaging system.

E3-1203: Fix issue where modifying certain wrapper files would cause failure

See merge request e3/e3-require!134

The issue was that `git status --porcelain` formats its output in such
a way that `make` no longer passes the variables correctly. The solution
is simply to no longer pass the `git status` data.

Note that the git status data already was not that sufficient in terms
of recognising what changes had been made, since all it provided was
information as to which files had been modified, not how they had been
modified.

E3-1215: Fix issue with multiple records that include dbCommon.dbd

See merge request e3/e3-require!133

E3-1161: Remove separate install_module target

See merge request e3/e3-require!130

This removal allows us to remove the `hdrs` target from every module; there
were only two modules that still used it, and they have both been fixed.

E3-1197: Fix possible memory issues

See merge request e3/e3-require!131

This was reported by cppcheck over require's code:
require-ess/src/runScript.c:128:12: error: Common realloc mistake: 'line_raw' nulled but not freed upon failure [memleakOnRealloc]
      if ((line_raw = realloc(line_raw, line_raw_size *= 2)) == NULL)
           ^

Unfortunately realloc can return null, in that case if we use something
like
line_raw = realloc(line_raw, size);
The memory pointed by line_raw is lost.

This was reported running cppcheck over require's code.

Partial reversion of af57525d

See merge request e3/e3-require!126

The issue is that `COMMANDLINE_LIBRARY` is used by EPICS base to link against
some other libraries; removing this line means that every lib*.so now links
against libreadline.so. This isn't _strictly speaking_ an issue because
`softIocPVA` also ultimately depends on libreadline. However, it is bad
practice.
