Kumar 0af08bcfc9 Process: Display single digit precision for CPU% greater than 99.9%
Since commit edf319e[1], we're dynamically adjusting column width of
"CPU%", showing single digit precision also for values greater than
"99.9%" makes "CPU%" column consistent with all other values.

[1]: edf319e53d

Change "Process_printPercentage()" function's logic to always display
value (i.e. "val") with single precision. Except when value is greater
than "99.9%" for columns like "MEM%", whose width is fixed to "4" and
value cannot go beyond "100%".

Credits: @Explorer09, thanks for the patch[2] to fix title alignment
         issue.

Charlie Vieth 0388b30077 Hashtable: fix handling of NULL pointer in Hashtable_dump
This fixes an issus in Hashtable_dump where `"(nil"` is passed as an
argument to `%p` in fprintf. This prints the static address of `"(nil)"`
not "(nil)". This commit changes the code to just pass the NULL pointer
to fprintf, which will consistently print "0x0".

Denis Lisov 4b8b61fe18 ProcessList.h: remove `ProcessList_remove`
As the "highlight dying processes" option has to keep processes in the
list when they disappear, no code except the cleanup loop in
`ProcessList_scan` should remove processes from the list directly.
Remove the export to prevent random process removals from being
reintroduced accidentally.

Denis Lisov fae7ff6f03 LinuxProcessList_recurseProcTree: keep on read error
If a process goes away while reading its fields, but we already have
that process in the list, we should keep it in case the "highlight dying
processes" mode is active. Not only is that expected in this mode, but
this should also ensure parents are in the list when their children are
(wanted for tree mode consistency).

Denis Lisov e07fce7014 LinuxProcessList_recurseProcTree: open dirfd first
A process can die between reading the directory listing and opening the
directory FD (if HAVE_OPENAT) or /proc files (otherwise) for reading the
process data. This race would cause LinuxProcessList_recurseProcTree to
remove it from the list immediately, which is unexpected in the
"highlight dying processes" mode and can break the tree structure.
This patch closes this race in the HAVE_OPENAT case by only accessing
the process entry after the directory FD has been opened.

Charlie Vieth 08166b27b1 ProcessList: fix quadratic process removal when scanning
This commit changes ProcessList_scan to lazily remove Processes by
index, which is known, instead of performing a brute-force search by
pid and immediately reclaiming the lost vector space via compaction.

Searching by pid is potentially quadratic in ProcessList_scan because
the process we are searching for is always at the back of the vector
(the scan starts from the back of the vector). Additionally, removal
via Vector_remove immediately reclaims space (by sliding elements
down).

With these changes process removal in ProcessList_scan is now linear.

Changes:
  * ProcessList: add new ProcessList_removeIndex function to remove
    by index
  * Vector: add Vector_softRemove and Vector_compact functions to
    support lazy removal/deletion of entries Vector_softRemove
    Vector_compact
  * Vector: replace Vector_count with Vector_countEquals since it only
    used for consistency assertions.

Nathan Scott cde72dd0b0 Remove redundant null checks on Settings_write (covscan)
Coverity scan reports that there is dead code in Settings_write
checking for nulls that have already been dereferenced on every
code path leading to the check.  This is likely a hangover from
times when the screens pointer was only conditionally allocated
- they're not needed anymore.

Nathan Scott cb61865bb9 Add array bounds checking for the Process_fields array (covscan)
Coverity scan reports there may be a code path that would cause

evaluates default sort direction.  Add bounds check and default
to descending instead of a potentially invalid array access.

Explorer09 ee1bf2f917 Process: Fix PID & UID column widths off-by-one error
If the max PID or UID value for a platform is exactly a power of ten
(10000, 100000, etc.) the column widths of PID and UID would be 1 char
less than the correct number of digits. This is caused by the wrong
rounding function (ceil(x)); change to the correct one (trunc(x) + 1).
