PM: hibernate: replace deprecated strncpy() with strscpy()

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

This kernel config option is simply assigned with the resume_file
buffer. It should be NUL-terminated but not necessarily NUL-padded as
per its further usage with other string apis:
| static int __init find_resume_device(void)
| {
| if (!strlen(resume_file))
| return -ENOENT;
|
| pm_pr_dbg("Checking hibernation image partition %s\n", resume_file);

Use strscpy() [2] as it guarantees NUL-termination on the destination
buffer. Specifically, use the new 2-argument version of strscpy()
introduced in Commit e6584c3964f2f ("string: Allow 2-argument
strscpy()").

PM: hibernate: Support to select compression algorithm

Currently the default compression algorithm is selected based on
compile time options. Introduce a module parameter "hibernate.compressor"
to override this behaviour.

Different compression algorithms have different characteristics and
hibernation may benefit when it uses any of these algorithms, especially
when a secondary algorithm(LZ4) offers better decompression speeds over
a default algorithm(LZO), which in turn reduces hibernation image
restore time.

Users can override the default algorithm in two ways:

1) Passing "hibernate.compressor" as kernel command line parameter.
Usage:
LZO: hibernate.compressor=lzo
LZ4: hibernate.compressor=lz4

2) Specifying the algorithm at runtime.
Usage:
LZO: echo lzo > /sys/module/hibernate/parameters/compressor
LZ4: echo lz4 > /sys/module/hibernate/parameters/compressor

Currently LZO and LZ4 are the supported algorithms. LZO is the default
compression algorithm used with hibernation.

PM: hibernate: Add support for LZ4 compression for hibernation

Extend the support for LZ4 compression to be used with hibernation.
The main idea is that different compression algorithms
have different characteristics and hibernation may benefit when it uses
any of these algorithms: a default algorithm, having higher
compression rate but is slower(compression/decompression) and a
secondary algorithm, that is faster(compression/decompression) but has
lower compression rate.

LZ4 algorithm has better decompression speeds over LZO. This reduces
the hibernation image restore time.
As per test results:
LZO LZ4
Size before Compression(bytes) 682696704 682393600
Size after Compression(bytes) 146502402 155993547
Decompression Rate 335.02 MB/s 501.05 MB/s
Restore time 4.4s 3.8s

LZO is the default compression algorithm used for hibernation. Enable
CONFIG_HIBERNATION_COMP_LZ4 to set the default compressor as LZ4.

PM: hibernate: Move to crypto APIs for LZO compression

Currently for hibernation, LZO is the only compression algorithm
available and uses the existing LZO library calls. However, there
is no flexibility to switch to other algorithms which provides better
results. The main idea is that different compression algorithms have
different characteristics and hibernation may benefit when it uses
alternate algorithms.

By moving to crypto based APIs, it lays a foundation to use other
compression algorithms for hibernation. There are no functional changes
introduced by this approach.
