* add default sort column, set by scols_sort_table()
* sort tree according to default sort column also in scols_sort_table_by_tree()
The function scols_sort_table() does not sort tree branches if tree
is not enabled. The function scols_sort_table_by_tree() does not care
if tree is enabled and it always follows parent->child relations. For
scols_sort_table_by_tree() we need to follow order in branches if
previously scols_sort_table() has been called.
For example lsblk calls
scols_sort_table(tb, cl);
scols_sort_table_by_tree(tb);
for list-like output (for example lsblk -P) and users assume the
same order as for tree (lsblk --tree).

For example for hierarchy:
$ findmnt -oTARGET,ID,PARENT
TARGET ID PARENT
/mnt/A 802 62
└─/mnt/A/B 937 802
├─/mnt/A/B/C 964 937
│ └─/mnt/A/B/C 991 964
└─/mnt/A/B 1018 937
└─/mnt/A/B 1045 1018
we need umount in order (id): 1045, 1018, 991, 964, 937, 802. The current
code first tries 991 in 937 branch.

Besides some formatting tweaks, I've changed »lsblk(1)« into »lsblk(8)«
in the SEE ALSO section of mount.8.adoc. At least Archlinux and Debian
ship lsblk as a system administration command.
Currently ARROW_DOWN and PAGE_DOWN is bound to command 's' (skip lines).
But this behaviour is not what the user expects, since at least one line
is always missing! Furthermore at the end of the file there is typically
this skipping lines message, if the remainder does not fit in a
complete screen. This conflicts also with e.g. less and man PAGE_DOWN
behaviour. The 'natural' behaviour is binding to
more_kc_jump_lines_per_screen.
If more is extended to also jump only a specific number of lines forward,
this would be even a better binding for ARROW_DOWN.
The whole thing is complicated by the fact that we have two layers
of libraries: e.g. libmount also needs libblkid. If we just tell meson
to make libmount static, this is not enough, because we also need it
to link to a static libblkid. Hence in the case of libs that link to
other libs internally, we need to create a different object with a
a different set of link_with items.
To avoid building the libraries twice, libfdisk and libmount are first
built into an internal "convenience" library, which is then linked into
the static and shared versions as appropriate.
To build: meson build && ninja -C build
To run tests: ninja -C build check
To install for packaging: DESTDIR=/var/tmp/inst ninja -C build install
To install for realz: sudo ninja -C build install
v2:
- Optional items are now based on the 'feature' feature in meson.
Built libraries which are disabled turn into disabler() objects
and also poison any executables which link to them.
What is there:
- building of the binaries and libs and the python module
- installation of binaries, libs, python module, localization files,
man pages, pkgconfig files
- running of tests
- most options to configure build equivalently to the
./configure settings
Partially implemented:
- disabling of stuff when things missing. In the C code, the defines
are all used, so that should be fine. In the build system, some
files should be skipped, but that is probably not always done properly.
Getting this right might require some testing of various build option
combinations to get the details right.
Not implemented:
- static builds of fdisk and other binaries
- things marked with XXX or FIXME
- ???
Differences:
- .la files are not created. They are useless and everybody hates them.
- Requires.private in pkgconfig files are not present in the
autogenerated .pc file. Not sure if they should be there or not. If
necessary, they can be added by hand.
- man pages and systemd units are installed by the install target. Not
sure why 'make install' doesn't do that.
- the split between / and /usr is probably wrong. But it's all pointless
anyway, so maybe we could simplify things but not implementing it at
all under meson?
