Lots more unit tests and code cleanup
Relevant changes from ChangeLog
o job.c: Print -de error information when running multiple jobs
o var.c: only report error for unmatched regex subexpression
when linting (-dL) since we cannot tell when an unmatched
subexpression is an expected result.
reduce memory allocations in the modifiers ':D' and ':U'
reduce memory allocation and strlen calls in modifier ':from=to'
in the ':Q' modifier, only allocate memory if necessary
improve performance for LazyBuf
reduce debug logging and memory allocation for ${:U...}
reduce verbosity of the -dv debug logging for standard cases
fix double varname expansion in the variable modifier '::='
o var.c: avoid evaluating many modifiers in parse only mode
in strict mode (-dL) many variable references are parsed twice,
the first time just to report parse errors early, so we want to
avoid side effects and wasted effort to the extent possible.

# Test behaviour of recursive make and vars set on command line.
|
|
#
|
|
# FIXME: The purpose of this test is unclear. The test uses six levels of
|
|
# sub-makes, which makes it incredibly hard to understand. There must be at
|
|
# least an introductory explanation about what _should_ happen here.
|
|
# The variable names are terrible, as well as their values.
|
|
#
|
|
# This test produces different results if the large block with the condition
|
|
# "scope == SCOPE_GLOBAL" in Var_SetWithFlags is removed. This test should
|
|
# be rewritten to make it clear why there is a difference and why this is
|
|
# actually intended. Removing that large block of code makes only this test
|
|
# and vardebug.mk fail, which is not enough.
