Fix following wpa2 enterprise vulnerability issues:
1. The station can complete 4-way handshake after EAP-FAIL is received
2. The station crashes if EAP-SUCCESS is received before PMK is setup
This prevents a device from being bricked in case when both secure boot & flash encryption are enabled and encryption gets interrupted during first boot. After interruption, all partitions on the device need to be reflashed (including the bootloader).
List of changes:
* Secure boot key generation and bootloader digest generation logic, implemented inside function esp_secure_boot_permanently_enable(), has been pulled out into new API esp_secure_boot_generate_digest(). The enabling of R/W protection of secure boot key on EFUSE still happens inside esp_secure_boot_permanently_enable()
* Now esp_secure_boot_permanently_enable() is called only after flash encryption process completes
* esp_secure_boot_generate_digest() is called before flash encryption process starts
Issue : Restarting the server without 30sec delay between httpd_stop() and httpd_start() causes EADDRINUSE error
Resolution : Use setsockopt() to enable SO_REUSEADDR on listener socket

Fixed adjtime function: While using the adjtime() function,
the time correction accumulated an error
when reading the time frequently (using gettimeofday).
When using direct operations instead of `esp_http_client_perform`, we need a way to set redirection URL when we get 30x response codes. Added the function for the same.
User can now check status code and call `esp_http_client_set_redirection` function to enable redirection.

Operation:
In `esp_http_client_set_url`, we check for if old_host is same as new_host.
Delete and open new connection if host is different.
Issue:
We just pointed `client->connection_info.host` to `old_host` and reassigned it.
This made old_host and new_host always point to same location and hence, using old_host with new request.
Fix:
Made a separate copy for old_host using strdup.

1. Softap support multicast and broadcast saving and flushing when the associated stations enable IEEE80211 legacy power save(which is called modem sleep in ESP32).
2. Improve the frame saving and flushing mechanism of softap power save.
Earlier eraseItem function in Storage class would do lazy cleanup of
multi-page blobs if called using type "ANY" instead of "BLOB". It used to
just delete BLOB data and index would remain as is. Any subsequent read
would delete index entry as well. This however would return a valid
length without error if nvs_get_blob API was just used for finding
length and not reading the complete blob. This change fixes this issue.

1. remove redundant SPI clock settings, use rom functions to set clock.
2. remove redundant SPI cs setup and hold settings.
3. for old 32Mbit psram, cs hold time must only be 0.5T due to the special driving mode.(cs_setup = 0; cs_hold = 0)
4. for new 64Mbit psram, cs hold time is recommended to be 2.5T. (cs_setup = 1, cs_setup_time = 0;cs_hold = 1, cs_hold_time = 1)
