Roberto E. Vargas Caballero f45156d5b4 Simplify expression in makeline()
This expression was wrong, but it was causing a false positive
in some compilers that couldn't see that error() cannot return.
The actual problem of the line is that it was too complex and it is better
to split it in simplex expressions.

Roberto E. Vargas Caballero 9781959581 Fix copy()
Copy was using directly the line numbers and incrementing them
without calling nextln(). It also didn't worry about how
line numbers are modified when we insert new lines.

All the ocurrences of addchar() were moved to addchar_(),

Roberto E. Vargas Caballero 20794b570e Define new String type
Current handling of strings is a bit messy. This type is copied
from the sed implementation. Addchar_ is added to be able to live
with String and old style chars based in 3 different variables.

Pieter Kockx 4b9c6645f5 sed: Fix parsing bug in find_delim
's/[[x=]//' was parsed as 's/[[=x]//' which (correctly)
raises an error because the "second delimiter is missing", here =].

The two got mixed up because the parser didn't return to
the "inside bracket"-state after encountering an opening bracket
while inside the bracket expression.

Pieter Kockx 6eec2eb3b4 tr: Fix infinite loop
When `makeset` got a string containing square brackets
followed by at least one extra character, e.g. "[abc]d",
it entered an infinite loop because it was assumed
`j` could not exceed `len` without having been equal to `len`.
It can, however, when `m == len` and subsequently `j = m + 1`.

David Phillips e1c56a6321 chmod: Use DIRFIRST
Previously, running `chmod 777` on a directory that had no read or
execute access (e.g. 111 or 000) would cause chmod to throw its
toys since it was trying to opendir before having added read permission
to the directory.

David Phillips 69b9c2444b libutil/recurse: only opendir if recursing
Previous behaviour was to call opendir regardless of if we are actually going
to be recursing into the directory. Additionally, some utilities that use
DIRFIRST benefit from running the function pointed to by fn before the call
to opendir. One such example is `chmod [-R] 777 dir` on a directory with mode
000, where it will be expected for chmod to first give itself rwx before
optionally listing the directory to traverse it.

Michael Forney c225d88d49 getconf: Report invalid variables as errors
Printing `undefined` to stdout means that the variable is valid but not
set. Instead, report an error in this case.

linux 4.13 appends the result of `getconf LFS_CFLAGS` to HOSTCFLAGS,
even if it prints `undefined`. This is arguably a bug in the Makefile,
but even so, getconf shouldn't report that unsupported variables are
valid.

This simplifies things a tiny bit, and is also necessary for setting the
date since mktime operates based on the value of TZ.

David Phillips 46495ea902 ls: abort a directory if we cannot opendir it
We should not try and perform operations on an invalid DIR* stream.
Instead, we shall let the error message be printed, and the return
code set (existing behaviour) and abort afterwards.

Michael Forney ea8622a4ce tail: Process bytes with -c option, and add -m option for runes
POSIX says that -c specifies a number of bytes, not characters. This
flag is commonly used by scripts that operate on binary files to things
like extract a header. Treating the offsets as character offsets will
break things in mysterious ways.

Instead, add a -m option (chosen to match `wc -m`, which also operates
on characters) to handle character offsets.
